I'm definitely not a guy but have a fun story. Last month I decided to do a mini shop hop myself to check out shops within an hours drive of me.
When I walked into the last shop it was pretty busy with a preponderence of men in there. My "gaydar" pegged at maximum. I have had tons of gay friends so don't think I'm a homophobe or anything. These guys were a riot and a load of fun. Outgoing and friendly and more then willing to start up a conversation. One in particular asked me what I was working on as I was picking out batiks for the block swap here. We chatted about all kinds of stuff and he was very forthcoming in amiably speaking about my choices. In fact I had one blue in particular picked out I wasn't exactly crazy about and it turns out he wasn't either but it was the only shade of blue they had that I thought would go with one of my batiks at home. They were so much fun. Another was picking out fabrics for a round robin and I started teasing him that he should try a mitered border and expand his horizons. The others loved it and chimed right in. They were all quite animated and vocal but I thoroughly enjoyed the entertainment. Turns out one of the owners was a gay man, hence the preponderance of gay clientelle. After the group left the other owner said she hoped they hadn't offended me in any way. I laughed and said "oh no the girls were a riot". Both people behind the counter at the time (the woman and another guy) lauged and said that was the perfect answer.
