First off no offense to any cashiers and not all of them do it. 1. First thing is when I walk in and ask about an item and they respond "if I have any..." as if they own the store or the item. Or as if they make the choice of what the chain store carries. Obviously this one doesn't apply to mom and pop shops. 2. Ok the first may be a bit of just me but all can agree with this one. When they freaking hand back money with change and put the change on the money and it creates a slide and the change goes everywhere unless your as caution as someone on a tight rope. 3. When some thing cost 10.45 and I give them a 20 and they say "out if 20". No I gave you a teeny but take it out of 50. Sorry it just seems like a weird question. 4. When something cost 6.70 and I give them 10.20 and they don't know it's 3.50 (I get 2 quarters back because I hate a lot of change in my pocket) and it takes them forever or they ask me what they owe me. Or even worse is say 6.70 and I give them 10.70 and they don't its an even 4. Sorry this has been bothering me for years. Haha.
