When I hold my hand out to take your credit card/money, please, PLEASE don't just throw it down on the counter at me. So rude.

When you come up to check out, it's very much appreciated that you unpack your cart/basket and put the items up for me to scan. I know it's a shocker I don't know all the SKUs for things in the store, so just help me out.

I have many, many more but these are the two I deal with daily that make me angry
