I've been asked to just stay in their chair for the day, donating blood. They kind of "ooh" when they get my arm because the vein is so "accessible."
Right out of college I had a job pushing people to buy photos after they came in for their "free 8 x 10." (I didn't last long...I hated it.) One guy was looking at pictures of his son, who was not an attractive kid. He asked me something like "which one do you think he looks good in" and I responded something like "well, I don't know him personally, which do you think captures his personality?"
He said "You're very diplomatic."
