(I work in a local chain tobacco store. I am in my 40s. A very young looking man comes in my store with a small child.)
Customer: “Can I get a pack of [Brand] cigarettes?”
Me: “Can I see your ID?
Customer: “I left my wallet at home.
Me: “I’m sorry, but the law requires I ask for a valid picture ID. No ID means no sale.”
Customer: *testy* “I have a four-year-old kid! I think that proves I am old enough to buy cigs!”
Me: “Even kids too young to smoke can make a baby.”
Customer: *literally rips his shirt open* “For Christ’s sake I HAVE CHEST HAIR!”
Me: “Yup. You have about a dozen of them. Congrats.”
(The customer takes the child’s hand and storms out, cussing and complaining about me being rude.)
