I've been taught that the only safe subjects to talk about in the salon are the weather and hair-but mostly hair lol. If the subject of conversation turns to religion or politics, it should be turned back to hair. Which leads to talk about buying products, which leads to a retail sale, which leads to more money in our pockets, which is why we are are there.
I agree with the not being judgemental comment. If the owners are judgemental, they have no business working with the public. I also hope that's not the case.
