I haven't been asked the one about being poor, at least not directly; however, I have frequently been asked by co-workers, "Do you have a car?" It seems to be implied by their tone most often that they expect me to say "no" to that question. Honestly, the one that bugs me the most is when people assume that I must be in fantastic shape due to riding my bike to and from work every day, as if bike commuting is something that can only be done by those in peak physical fitness (I'd much prefer that anyone believe they could do it). My commute is only five miles one way, so there's a lot of additional exercise that I could be doing...
