I work in a supermarket and have done for over 5 years. For 4.5 I worked as a checkout assistant in Sainsbury. Customers come in all shapes, sizes, colours, genders and attitudes. Whilst it is sometimes frustrating dealing with a customer on the phone, the quicker you serve them, the faster they are gone from your till. It would be quite a game scanning at your fastest rate and watching the one handed customer try to keep up.
However, they are not the worst customers. I have said hello to customers to be completely ignored, not a word said to me. I am also often treated as dumb, yet I have a degree from UMIST, and have also completed 2/3 of a degree from the Open University. A significant number of colleagues also have good educations. We sometimes choose to work in retail for all sorts of reasons. Mine is depression and the shop is a fun place to work.
However the worst customer was one I never met. I am transgendered and was working in Sainsbury for the 2 years or so before I was allowed my surgery. One elderly female customer went to one of my supervisors to ask "why do you employ a thing like that?"
