Gift certificates. Perfect reason for them to cut corners. They look at it like "f'it, he'll be happy, its free to him". "Put it on there and he won't ***** cause he didn't pay for it." To hell with that. Somebody paid for it, do it right damnit. Typical business who doesn't car about their reputation. I'd tell them to rip it off, clean your windows and give you a cash refund, or do it right and keep the money. Either way, they won't be in business too long with an attitude like that.
