In my industry, picture framing, homophobics just do not seem to do all that well, for some reason.
I only had one problem in my 45 years of framing when a gay customer must have assumed I was also gay and started into this long story about a gay party he attended. It was one of those "way too much information" deals and I had to stop him and explain that I was not gay. He seemed to understand and changed the subject. He had been a great customer for years, but I never saw him again.
Personally I don't care either way about anyones orientation, it's all a part of humanity, it is what it is. I still feel bad about that incident though. I probably should have let him ramble on and not said anything, I don't know.
