I have a customer that constantly changes his logo. It's awful too, it's a low res image that he shifts slightly side to side over the text, then he makes small changes to the text itself. Nobody would know he's made the changes because his logo blows anyway.
I don't care because I bill him to rescan his new designs and we print them on the digital printer, so I don't care. He just needs to focus on something else other than his logo.
