At the grocery store.
Checker: I’ll need to see some ID.
Me: What, for that? It’s non-alcoholic beer.
Checker: [Flustered] It is? Oh, uh. Well I still need to check your ID.
Me: What, you think I’m a 19 year-old trying to buy non-alcoholic beer?
Checker: [Recovering] No. But I won’t sell you non-alcoholic beer if you’re over 21. It’s the principle of the thing.
You win this round, Mr. Smartypants checker guy.
