Tara Smith is off at a science conference, and she tried to buy some souvenirs from a Retail Sales Guy.
[RSG]: But you can't be a scientist!
[Me]: I can't?
[RSG]: No, you don't look like a microbiologist.
[Me]: Um, what exactly does a microbiologist look like, then?
[Me]: Because I'm pretty sure that I am one. (Rummaging through bag, digging out ASM nametag). Yep, that's my name, and that's the microbiology conference logo right there.
[RSG]: But you're too pretty! You should be in Hollywood.
Wait, you mean it's not just an atheist problem? Women, I don't know how you cope: you're held to a higher standard than men on your looks, but at the same time, if you're looking good, you're judged not smart enough to be a scientist.
I have had the opposite situation, though, where people look at me, guess my occupation, and say "college professor". I don't quite know what it is, because I do share a family resemblance with my father, who was a diesel mechanic (but didn't have a beard. That must be it!)
