[tracilicious]

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.
