I don’t understand at all the problem some folks have with bare feet. Personally, I’m much more comfortable shoeless and tend to be that way most of the time. I don’t know how it would go over in the office (though they don’t seem to complain about seeing my socks fairly often) but I often go to class barefoot in warm weather.
Yeah, I think you were rude. I’m all for folks keeping body parts to themselves on the bus, and if you wanted her to move her feet (shod or no) away, you were perfectly reasonable in asking her to. But to imply that her feet were dirty (when, as has been pointed out, they’re probably much cleaner than her shoes. Or your ass.) was quite rude, as was asking her to put her shoes on. I admit I’m biased, as I greatly enjoy going places barefoot, but it’s not generally done to tell acquaintances that parts of their bodies are a risk to public health unless the risk is quite significant (rules about hairnets and the like in restaurants obviously notwithstanding; this is outside the purview of etiquette.) Besides, how in the world is her bare foot any dirtier than everything on the bus? Buses are filthy, filthy things, and her feet are nowhere near as dangerous as the germs already doubtless blanketing every surface. If there was a sanitary danger, it was to her, not you.
Feet are not dirty. They are not inherently contaminated, though admittedly when closed up all day they can grow bacteria (as with the entire human body.) However, going barefoot more probably would result in dryer, cleaner feet. And her ass was sitting on a seat, protected by nothing but a little bit of cloth. The digestive system plays host to millions upon millions of bacteria, and here she is resting the end of hers on the seat!
The human body is a disgustingly filthy thing if you think about it, so it’s probably best not to (I sure don’t.) It doesn’t make sense to me to freak out over one potential exposure to germs when I don’t, for example, leap to wash my hands with anti-bacterial soap each time I blow my nose during allergy season. You’re exposed to other folks’ germs and bodily secretions constantly, and this was a pretty minor example of it. Either cocoon yourself in a plastic bubble, or learn to live with it.
But again, asking her to get her body out of your personal space is perfectly acceptable.
