Cripes. No wonder I never wanted to work at the beer store. (Well, besides the fact that I hate beer and would have given lousy recommendations to customers.)
Jesus H Buddha on a Stick! If it were known that the poor bastard clerk would be fined $10,000 for slipping up, I don’t see why any customer would object to being carded.
Now you know why I was so careful and thorough. 
It would be so much more convenient if they did though. You’d just have to take your cap off whenever you wanted to enter a club or buy a beer.
