Jeff D...
I once ran into (info was posted on TFL) a no-carry sigh on a majior FOrd dealership on Plymouth Road in Livonia Mi.
I went there, and sure enough, on the front door, there it was...
I waited in the lot, and a salesman showed up, so i talked to him about a nice 50 thousand dollar f-350 4x4 super-crew with all the options, even gave him my credit info. (the whole time remaining OUTSIDE the building!)
AFTER he had ok'd everything, and he had "made the sale" (except for me signing paperwork) he asked me to come inside and sign for the truck... I feigned "noticing" the sign, and informed him that I could not in good concience purchase a vehicle from a place that didn't believe in my right to defend myself...
he brought out the manager, who said they could "waive" the requirement, and met me in "while armed" to buy the truck...
I told them to go urinate up a rope... and said i thought i'd go to their competition, Dick Scott Dodge on Ann Arbor Rd. and buy a Dodge, since THEY weren't trying to infringe on my rights...
2 days later, I drove into that ford dealers lot after hours, and the vinyl stick-on "no gun" signs were GONE from the door!
