The same thing happens to me when I buy scrapbook paper. It's pretty expensive .59 ea.
so I usually wait for the sales 6 for .99 cents, and I buy a lot. When I go to the clerk they usually give me a weird look because they have to ring "each" piece separate.
I often offer to help and they change their attitude towards me. I agree that when they are rude you should talk to the management and make them aware of the clerks behavior.
Or on your way out you could tell her,
I'll be back tomorrow for more..
