Yeh you do have to be aware of that sort of thing like going to the pub and stuff chances are someone will spill their drink or something. I almost had someone throw up on me they threw up all over the pavement right infront of me. I'd have been livid had they gotten anything on me. But the other thing is if you're willing to spend huge amounts on clothes and shoes you've got to be willing to put up with the fact that some knob might damage it. It'd suck but to be constantly worried about it is just pointless in my opinion.
