When there is a long line in the grocery store & people (usually I hate to say, women) don't bag their own groceries. They have a 847 items & wait for the cashier to bag. That is pure laziness & wastes the time of everyone behind you. Plus, ladies, don't wait for the cashier to tell you the price to then start digging through your bag for your wallet. The lady in front of me today stood there until he told her the total then took 10 minutes to find her wallet, find the right card. etc. Ugh.
