i was in the area and decided to stop by. a very nice girl named Lisa paged for a manager and i talked to a management chick named Ashley. she was very helpful as i described the situation and also mentioned the very helpful Mark. she was highly displeased at what LG and BE had done and promised she would find out who they were and give them a good talking-to, and that it was not Home Depot policy to behave like that towards a customer.
i also mentioned Mark and his extreme help and that he really deserved some kind of kudos, and she said she would see to that too.
so here's hoping the bitches get properly busted and Mark gets a gold star!
