(This exchange occurs at least twice a day)

I work at a store that mainly sells smoothies, though we also offer several food items. Since the smoothies are rather large, we offer combos with a smoothie and either a half sandwich or half salad.
Me: Hi, how are you?
Customer: Good, I’d like to get the smoothie and a half combo *proceeds to stare at menu for a good while*
Customer: Can I get a half wrap?
Me: I’m sorry, unfortunately we can only do that with the sandwiches and salads.
Customer: Oh ok. *Proceeds to get a half sandwich or gives up and gets a wrap*

I have no idea why nobody seems to have a clue why we don’t serve half a wrap. What do they think would happen to the other half?
