From what I've observed in the past - and I'm not trying to be judgemental or obnoxious - the types who don't mind being cashiers for years are grandmotherly older women. I think it's a little less difficult for them because, due to their age, they often get *slightly*...notice I said *slightly*...more respect from customers right away. Customers are also more likely to believe that they know what they are talking about, and don't argue with them as much or question what they say about store policy. Again, this is just my experience.
