I'm pretty good at being able to spot someone in public who is trans* but only because I know what to look... for given they are things I'm trying to "conceal" myself. Other people know, or think they know, for whatever reason... ->-bleeped-<-, ally, hater, trans* curious, whatever. Regardless of his motives the guy was a jacka$$...rude and insensitive, quite happy to intrude into your space and kick the cart. Sorry it happened, hopefully it will be an extremely rare event into the future.
