A couple of one-liners from the time I was working as a Food Services supervisor in a large movie theater :
(At the Burger King counter)
Is there any cheese in your combo #2? (The combo was Cheese Whopper)
Yes, I'll take a cheeseburger combo with large fries, a pepsi and no cheese, please.
Client : I'll take a hamburger, with no meat, please.
Me : Uh, do you mean a Veggie-Burger?
Client : Ugh, I hate those. No I'll just have a burger with no meat, please.
Me : You mean you want just the bun, with two pickles, ketchup and mustard?
Client : Yes.
Me : ......Can do.
(At the main concession stand)
(I'm standing in front of a popcorn machine)
Do you sell popcorn here?
(At the pretzel stand)
What are your pretzels made of?
