Yesterday, I went to JoAnn's Fabrics to purchase a gray Sharpie. When I got to the registers, I met the ultimate SS customer. This woman waited until the cashier rang up the items and told her the price before she pulled out her wallet and fumbled around for her money. She gave the cashier the cash, which wasn't enough. She then put her money back and pulled out 3(!) different cards and told the cashier that she wanted $10 on one debit, $10 on the second, and the remainder on the third. The cashier took the first card, swiped it, then asked the woman to put in her PIN. The woman scooted to the PIN pad, fumbled around and messed it up, so the cashier had to ask her to re-input, upon which the whole amount was debited to the first card. Well, this woman started yelling at the poor cashier, who called a manager to the front to straighten it out, and asked the woman to move to the main register to wait for the manager. The woman refused to budge, so the cashier had to walk away to another register to help the rest of us (by this time, there was a long line of people). Until the manager arrived (about 2 minutes), the woman was yelling to everyone entering the store or walking near the registers "are you the manager?" By the time my transaction was complete (I had one item), the manager was working with the woman, who was loudly badmouthing the poor cashier. I asked the cashier if she wanted me to call the store manager to back her up, but she said the woman was a known problem customer, who pulled these antics to get a discount from the manager.
