DH and I were at the hardware store yesterday. This is a fairly large chain with a VERY generous return policy. As in, bring it in with in 90 days of purchase and you get cash back, store credit, exchange, whatever you want, even if your reason is just "I already used it but changed my mind." Yes, a VERY generous policy (DH once saw a guy return an electrical generator that still had gas in it because it "wasn't what [he] expected").
This guy was pitching a fit at the register because the manager wouldn't give him cash back on some piece of equipment. Reasons: Guy admitted he bought the tool 6 or 7 months prior (so, already at least 90 days out of return period) and he had NO receipt to show what he paid for it or that he had even bought it there.
The guy thought the store should give him his money back anyway because, according to him, the tool never functioned properly from the time he purchased it. He tried to use it several times but it was never right. Um, ok? So why didn't he bring it back within the 90-day no-questions-asked return window??!
Guy eventually gives up and loudly gives his parting shot as he storms out: "I guess my $30 lesson today is to never buy anything here again!"
