Back in the day, I would have said you would have had to live with the sticker or the ghost of the sticker :>)
I'm depending on the "more up to date" fellows to be giving you the right poop.
I bought a new car that the dealer had slapped one of his stickers on the trunk. Hadn't been there where I signed the papers. When I ask him how much a year he was will to pay me to be his rolling advertisement he blew a gasket. It was removed but I lived with the ghost of his tantrum until I got rid of the car.
Just saying, some people don't realize streets go two ways. I never had to say a word, when someone asked how I liked the car and the service, I just walked them out to my trunk with one comment "I asked him to remove it." (pointing at the ghost)
There are a lot of things God may get me for, but I don't think that will be one of them.
