a couple i've heard from customers that use home depot sometimes.first was a painter. he was doing an apartment building so it was off the shelf stuff.he went to the paint department and got his order filled,did the job and a few days later went back and had the same order pulled again . then he took the supplies right to the return desk with the origional receipt and got his money back! second was a window installer. he went and placed his order and when they came in he said the measurements were wrong.threw a little fit and left.later he has one of his guys go there and look at windows they can't sell for full price cuz they don't FIT anything and he buys all the ones they need for 1/3 of the price. anyone else hear some good ones?
