The only part that I don't like about shopping these days is when the SA makes any assumption about what you are buying something for... could be car parts even...its just none of their business. If you need a story, then use one... I think the SA should be profffessional enough to go along with what ever you tell them if they believe it or not. But, it does make it easier if you are open with them because then you are working towards a common goal.
