When you're on cloud nine but they're just trying to clock out

Former night clerk at convenience store.

Stoned people are fine. You're chill. Drunk people though, they are unpredictable and liable to do stupid or dangerous things.

I'm guilty of walking through a drive thru at 2am for this reason. However I did at least leave a $20 tip for their inconvenience (a long time ago, it was much more than the order itself).
