Customer comes through the drive thru..
Customer: I want a potato and a side salad, but does the potato have butter on it?
Me: No, the butter comes on the side. It doesn’t come directly on the potato.
Customer: Ok, I wan’t a potato, but make sure theres no butter.
Me: Ok, no butter.
Customer: Does that side salad have cheese on it? We have allergies so I need to make sure no one touched any butter or cheese while making them.
Me: There’s no cheese on the salad, and no one will touch any cheese or butter while making your food.
Customer: Ok, thanks.
*5 minutes later*
Me: Hi can I take your order?
Customer: Hi I was just here and I need to make sure there’s no butter on this potato. Is there butter on the potato?
Me: There is no butter on your potato.
Customer: Ok and no one touched any cheese while making any of this? I just need to make sure before I let my daughter eat this.
Me:

For the love of god, if you are so damn worried about it go home and make your own fucking salad and potato.
