We've been interviewing contractors for another large home project.
With the last guy, who comes highly recommended by a friend, he brought his new partner.
During the interview, I commented that we had also talked to a design/build firm that had a kitchen designer. The partner put up a limp wrist, and said with a lisp, "well we know what they are like".

Me - figurative jaw dropping to the floor. Immediately I said, "That is really offensive".
On the way out, he apologized, but after losing sleep for three nights, I told DH that we were not going to hire these guys, period. There were a few other factors that added up anyway. He was on the same page as me.

I called the main guy today and told him we were not going to hire them, so please don't make a bid, and this is why: that comment was offensive, inappropriate, and unprofessional and I just can't have that in my house.

Whew. I am glad I said it. It was the right thing but still feels kind of crappy to have to make that call. I mean, really?
People don't have to have the same value system as me, but they sure don't have to say stupid bigoted things in a job interview either.
