First, i am not a dude, and second, I was a cashier for a total of between 3-4 years. I know the policies, and I know that you know the policies. I have worked the express lanes when people have come in with full baskets and such and yes, even though I wanted to say "this is an express lane", I wasn't allowed. So when other customers complained about it, I just tell them, "complain to my boss, because we aren't allowed to turn them away." And if you are the kind of jerk who would smash someone's food just because you HAD to do your job, well don't worry you probably won't have it much longer....
