I manage an automotive paint store. Our motto is service first, service before anything. Give good service and the money will follow. Although 99% of our sales are through the phone or our salesman on the road we do operate a showroom for the walk in trade. Every customer is given any amount of time that is required to help them. It is rare that we would have multiple people waiting but somtimes it does happen. If I'm waiting on someone who wants to tackle painting their car themselves, that is going to be awhile. If I'm alone and there are others waiting I will ask the customer if he minds if I take care of someone who might only be there for a box of sandpaper. You try your best to help everyone in a timely manner. It sounds like the lady may just not have good people skills, ot at least doesn't have the abilty to multi task. Ditching a customer though for another however would not be accepted at my store - ever. I would go back and give it another shot and see it it is any different. If not, well there is always Tower.
