Okay, having read all the post to this thread and will soon be a "FROG", I'm the guy you don't want to get in front of at the grocery store in the "10 items or less express lane" with a cart full of groceries. The cashiers can not tell the customer they are in the express lane, so who does that leave it up to? YOU and I!!!!
I'm not rude about it, but I don't mind saying anything. It will be the same way anywhere else. If I see an unsafe or stupid act, I'm not shy and will "call it to your attention"!
You can be diplomatic about it (which is defined as "stepping on someone's shoes without hurting the shine").
Having been a Scout leader, I'm all about correcting and teaching young people about safety and following rules.
