yep, don't take your eyes away when your fabric is being cut. Always check the slip they write stuff down on before you go to pay. Naturally, we want to be good customers as we stand there waiting nicely but it's OK (make that a really huge OK) to be the pain-in-the butt customer that makes sure you are getting what you pay for. Ask questions, make sure sales items are marked, take your own notepad and calculator and tally up what you should be paying. It may be a few cents off from the register but MAKE SURE any questions are answered before you hand them your credit card. By the way, if you did pay with a credit card you might be able to get the purchase reimbursed by disputing it with your card provider. They investigate and charge the store back if the store screwed up.
