Never let a woman in front of you in line - she'll wait to watch the item get run up, then she'll see if she has a coupon then complain because the coupon doesn't match the item, then she'll dig through her pocket book to find her wallet, then ask for a bottle of wine, then complain how long the registers take at this place, then decide she doesn't want the item she got in line for since she can't use the coupon and jam it into the candy rack to show her disdain for people who can read.
