When I encounter terrible customer service from employees of a store, I dig in. I make it almost impossible for them to ignore me. I ask as many questions as I can think of, I ask to be shown many many items, I ask about sales, quality, price comparisons, if they can't answer I ask to speak to the manager or ask the manager for the number to the home office. I will make a purchase but only after I have gotten the price of the item in their time spent with me. After a few times of this, I am greeted by name and helped as fast and nice as possible to get me out of there. LOL
