Sundial, great story.
My experience in bike shops (when I'm noticed at all) is that they act very uncertain because they can't categorize me. I'm old but not overweight. It's kind of fun (when i'm noticed at all)

bad experience: when i was trying to get my bianchi to fit me, we decided we'd put a steel fork on it. I went to the bikeshop (eastside bikeshop) without DH so it was just me and the people that work there; all 30 and under. I told them i wanted a steel fork and 4 or 5 of them insisted that carbon was better... They actually ganged up on me!
So i wasted my $$$ and got another carbon fork. I got home and DH said "I thought you were getting steel?!?!?" I was outnumbered, they didn't listen, they all knew SO MUCH MORE than ME.

I did not buy a bike from them.
