Stereotypes?

Q: What do you call a short person with glasses, a hat, a T-shirt, shorts, and something interesting to read?

A: A scientist!

Apparently there's something about that appearance that screams "scientist" to a lot of people. I went to get some take-out food, having decided that I've had enough spinach and bell pepper salad, and after I placed my order for something filling, the person at the counter looks at me and just says "Hey, you're a scientist, aren't you?" I was tempted to ask what science, but I decided against it because I just wanted my food, having been hungry for quite some time. The real fun, though was when I had to set my reading material down next to me so I could sign the receipt and the cashier looked horrified when she saw what I was going to read while waiting. I had an issue of Traditional Bowhunter with the page turned to a review of a really cool high-powered compact longbow, complete with broadhead-tipped arrows and a picture of a hunter with an animal they just shot. Is it me, or is it just that nobody seems to expect a 5'2" Asian female scientist in training to be interested in bow-hunting or to be able to draw more than about 30 lbs?
