Reminds me of a restaurant that used to exist called 'Sambo's'. It was named after the founders: Sam Battistone and Newell Bohnett, and they had to rename it or something after PC came into vogue. I suspect Bosam's wouldn't have gone over well either, especially if they'd used the other lower-case a. (very similar to an o, which could make the sign look like 'Bosom's' from a distance.)
