Who do you think you are?

You’re at the grocery store.  You’ve got lots of groceries on the belt.  There’s no bagger.  Oh, and there’s lot’s of people behind you in line.  The cashier’s bagging your groceries as quickly as she can, it’s taking forever.  Instead of helping bag your own groceries you stand and watch her.  Hey douche bag, lend a hand you’re holding people up.
