I would like to bring up the issue of proper etiquette while waiting in line for a product launch. I have never waited in line for a launch or camped out. Will those of you who have experience doing this, please offer your advice and any do's and dont's for waiting in line? One question I have is regarding going to the bathroom. If I need to go to the bathroom and have become acquainted with either the person in front of me or behind me, is it ok to ask them to hold my spot while I run next door to use the rest room?
