(I am serving a mother and her teenage daughter. There is a limited edition version of a popular type of gum. The daughter picks up a packet.)

Customer: *looking outraged* “I’m not buying you condoms!” *slaps the gum out of her hands*

Customer’s daughter: *embarrassed* “They’re not condoms!”

Customer: “Or…whatever they are!”

Customer’s daughter: “It’s gum!”

Customer: *embarrassed*

Customer’s daughter: *even more embarrassed and turning bright red*

Both of them: *hurriedly pay and leave, without the gum*
