I'm sorry, the way you retold the story sounded hilarious (because I could care less what ignorant people think) UNTIL you got to the part where you told him he clearly had better things to do than to help a paying customer and he said ok and walked away

.  Holy smokes, are you kidding?  Especially in this economy.  I think you should call the store and speak with his boss.  That was appalling. I cannot tolerate rudeness and I just see more and more of it lately.
