I'm going to have to agree with GD and Alex here. Getting annoyed over a few seconds (or even a few minutes) seems silly. Big deal if they get their card out before or after their stuff rings up. I try to plan my activities so that the extra 20 seconds won't make me unreasonably late for anything. Better to be pleasant and focus on enriching others lives than be grumpy and spoil your own mood.

300 Million - well Hell, I think we need to go to China or India and do some benchmarking on their populations to make sure we're scalable.

I usually have a sudden desire to test the effectiveness of my braking system.

I usually get my car out of the way, as I've had the unpleasant experience of suddenly realizing that another motorist in a much larger vehicle is actually trying to force my car off the road - and into a concrete retaining wall. At freeway speed.

Guns are real fun as well, Prudence. Let's just say I don't flip people off quite as frequently as I used to....

There was a made for tv movie(name escapes) I saw some 20-25 years ago in which a man had a child(I am not even sure if the child was a boy or girl) who had a terminal disease. In the childs last hours a request was made for a bottle of soda. The man went to the store, frantically looked for the beverage, finally found it and then got into line. The woman in front of him saw that he was in a hurry and deliberately took longer to finish her transaction in order to teach him a lesson in patience(she didnt say anything to him, but it was implied that this is what she was doing)....a lesson he didn't need for he said not a word to her.

It was just a movie I had totally forgotten until this thread. Not likely that someone your holding up on purpose is in any kind of similar situation but still...................
