I haven't counted it up, but it feels like there are more people in this thread that are upset about people who write checks, than people who essentially jump in front you in line. It's not so much that I'm more annoyed at check writing than I am line jumping. Line jumping in it's self is a much more heinous act. However, the way it was presented in the first post of this thread is questionable. There are too many different scenarios in that situation. If another line opens and you notice people in front of you making a motion to go over to the new line and you race over to beat them, then yes, that's definitely rude. However, if the people are not paying attention or just look over and seem to not care or have no interest in moving over to the new line (I see this a lot), then I'm sorry buy I'm not going to wait for them. Or, lets say there are 6 people in line and a new line opens then who should move over. In reality 2, 4, and 6 should move over. However, how often do you see this exercised to perfection? Also, what if the 5th and 6th guys have 1 or 2 items and the 2nd, 3rd, and 4th guys all have 10 items or more? I really think the guys with less items should be able to go first, especially if they are paying with cash or check/credit card. Also, in a place like the average grocery store or Wal Mart or Target its nearly impossilble for the 2nd or 3rd person to work their way out of the line and go to the new line. At Walgreens, usually the registers are right across from one another and it's easy for anyone to move over. There is no simple yes or no to the original question of this thread. I don't know if there is too much that angers me more than someone just blatantly skipping in line. Fortunately, I don't see it happen to often. If the situation described in a previous post about the skipping at a golf course happened to me, I would be very vocal and make sure I was heard.
