"I Worked at Del Taco for a year when I was in high school. 

One night I'm taking an order as usual from the drive thru. Car pulls up and there's a cleanish looking guy in the driver's seat and a very scantily dressed woman next to him. I make small talk as I get the money and I finish the order. When I'm handing the food to the car, the guy asks me, 'So how long do you work tonight? Wanna come hang out after?' 

I replied with, 'Well I'd love to, but I'm only 17 and I have school tomorrow.'

The guy just shoots a quick 'Oh s**t!' and bolts... I think they were trying to get a threesome going."

"My store was a block away from all the major clubs in town so naturally it was packed that night. Thankfully, across the street was our police station and a couple of officers would always be in the store to deter idiots from doing something in the dining room.

I took an order and heard them lightly giggle through my headset so I called one of the officers over. The guy grabbed his order and threw a bowl of chili. I closed my window and locked it just as the chili splatted on it.

 As far as I know they didn't get arrested but did get a nice ticket."

"So a girl and her boyfriend come through the drive-through, get their food, and take off. Next car pulls up and it's a guy just bawling his eyes out.

Turns out the girl in the car ahead of him was his girlfriend and she was cheating on him with the guy."

"Once this dude was so f***d up that he tried to order a Big Mac meal. I told him like 20 times that we didn't serve Big Macs because this was Kenny Roger's Roasters, a chicken joint. Finally he screamed 'F**K YOU B***H' and roared off."

"I am a cook at a Sonic Drive-In. A few years ago, I was working night shift.

This guy came through the drive-thru and ordered a Brown Bag Special (two burgers, two fries/tots, two drinks). Before we could hand him his food, the guy got out of the car, threw his drinks at the car behind him, got back into his car, floored it in reverse (hitting the car behind him) and drove off.

The manager calls the police. During this time, the guy from before COMES BACK to Sonic, parks in a stall, and says to the carhop that he forgot his food. Obviously, he was arrested."

"One night a customer came up to the speaker and I asked, 'how may I help you?' From the other I end I get a yelling response of ....anger? 'HOLD ON! ITS MY TURN ON THE BONG!!'

When they came through, they did in fact have a bong in the front seat."

"This is about 10 years back in Nelson, New Zealand. A customer took the change he was about to give the girl, put it in his mouth, swirled it around a little to get it all stinky, spat it out and gave it to her."

"At my Baskin & Robbins everyone who's working has on a headset at any given moment. This one time a dude comes up and orders some ice cream thusly: 'and a double scoop of chocolate on a sugar cooOOOOOOONE!' We all just turn to stare at each other like, 'what the hell's up with this guy?'

When my coworker opens the window for him, she subtly ushers me and the other coworker to look out the window. The guy's got a damn towel on his lap and the girl next to him is wiping her mouth."

"I'm not an employee, but I was visiting Houston, Texas one time and driving from the Airport I saw three overweight men on horses 'pull up' to a McDonald's drive thru. As a visitor who'd been in the state for less than an hour it quite quickly confirmed a few stereotypes!"

Told by a Guff staffer

"This lady with a van full of 14 children ordered 15 ice creams cones in the drive thru. It was a very hot day and we were filling the ice cream machine literally as she was ordering. I made as many as I could (13) before telling her I'd have to wait two minutes for the ice cream to freeze. She went ballistic and demanded her money back. I gave her the money back for the ice creams she hadn't received and she got furious demanding all the money back. 

She became increasingly aggressive and my manager had to tell her to leave and close the window. I turned around for a second, and when I look back, she'd smeared all her children's half eaten ice creams all over the drive thru window! She even came back inside to demand all her money back because she'd 'given the ice cream back'."

"Long, long ago, when I was a teenager, a guy who was super drunk drove his car through the menu."

"I'm a manager at McDonalds, and I've heard some crazy stuff. One of the worst was a women having phone sex before placing her order. (She thought we couldn't hear her.) it was so bad that I had to tell her to stop because there are minors working here that could hear her. She promptly drove off without placing her order after saying 'oh shit'."

"I once had some moron order 50 Jr Bacon Cheeseburgers. We loaded the grill, laid out as many buns as we could find room for and punched in the order. While waiting for him to find his wallet about 20 of the sandwiches had been made and bagged to which he said, 'PSYCH! HAHAHA' and sped away, leaving me with about a $60 tab of voids. Voids were a BIG no, no and grounds for termination."

"Late-night snacking is bothersome as you can only order by car. Once as a drunken customer I went through a drive thru crouched down as if I was driving an invisible car. My friends were in the 'back'. Unfortunately the cashier wasn't fooled so we had to call a taxi to make the drive. It may have been their shortest ride ever."

Told by a Guff staffer

"I was taking someone's order and their car was busted by undercover cops. Working at McDonald's gave me the craziest stories."
