'Ice Tea' Lady

So this lady comes in the store with her big cup of 'ice tea' for the 3rd or 4th time now. She bangs her way through the door with her rolling shopping cart, comes over to the counter plops her cup down and parks her cart right in front of the counter. She brings some books for trades and gets 3 credits. She goes into the romance section moves stuff all over and out of order, gets a half dozen, brings them to the counter. She only has credit for 3, so she's only going to get 3 of them, but she can't remember where she got the rest from, so she leaves them on the counter. Then she finds a hardcover book, and asks how much it is, $6.95 it's priced on the 1st page, I tell her. How much? she asks, $6.95 I tell her. How much? she asks, $6.95 I tell her beginning to really wonder at her. She walks over to another bookcase, and calls back how much is that book again? It's still $6.95 I assure her. She comes back to the counter and points at the book. How much is this book? she asks a fifth time. I open it up and point to the price written inside, it's $6.95 I say yet again. Eventually she leaves, not purchasing it. I wonder what was really in that cup of 'ice tea' ?!?
