I walked into a local yarn store in a state far away. As a male in a yarn store, I am used to the "Are you looking for your wife?" look. At this particular shop, the "You are in the wrong place" attitude was practically shouted at me.
One of the ladies finally asked, "What project are you working on?' I said, "I don't knit." And three heads nodded (all knowing) Then I went into slam mode. "I spin, what roving do you have?" None. Yea, they can't knit without spinners.
Thankfully most aren't so rude. One shop across the street from the Mayo clinic even had a guys corner with chairs and magazines of interest to non -fiber guys.
