These rude sales people usually get a hammer from me. It's their job to be polite and professional. I will call out the person everytime. I recently called out a store manager for lying to my face... Ticks me off because I don't look my age and people think they can be snot nosed people and do as they please. They pull a 180 when they realize I know my rights and they are the ones that are supposed to be professional not me. On the other hand I'm a good tipper and always praise a sales person for going out of their way. I used to be a salesperson myself so I know how it is.
