Hi Red: I used to feel nervous too going to the cash and sometimes waited until no one else was there. However, in a busy store you can't always do that. Another thing that bothered me was buying new things I didn't know much about and hoping I had the right ones. It's easy to get flustered then. When waiting with all the commotion around, I would focus on any art work hanging on the walls, posters, etc. I would try and figure out the colour of the walls, what do they use for window dressing. Things like that. Another way to keep things straight in the confusion of the moment, was to have a pen handy so I could cross off my list the items I purchased. Maybe you could do that if the cashier waits on someone else while serving you. It was easier to see if I missed anything. Hope some of these ideas are helpful to you. Good luck tomorrow if you go back to the store.
