You know, I have to agree with unmagical on this one. It's gotten to the point where if I want to just run into the shop for a quick trip there's a mental list of things to avoid that will cause trouble. I'm of the opinion that if I have to change my behavior to avoid something putting up artificial roadblocks for me, then that system is a failure. Case in point I went to CVS to buy some cough medicine for my kid the other day and discovered that cough medicine is now age-restricted. Instead of letting me scan my driver license (you know cause the kiosk has a bar code scanner and my license has this fancy new bar code) the clerk has to come out of whatever dungeon he was in to put the mk 1 eyeball on me and give the kiosk his blessing.
