I used to do craft shows and heard these same things.
I have a few favorite shows I still go to. DH went with me last year. I absolutely fell in love with a santa. Dh says a little too loudly...."You can make it." I looked at him and said."Probably could, not gonna happen and it wouldn't be this cute." That Santa was a hit in my living room. If that seller is there this year I will buy another.
That will teach him to have manners...or to stay home.
