Common sense really comes into play when on stilts, Id like to bock around/inside a bus/train station, but I thought to myself it would be in everyones best interests if I wasnt on them in case I did fall over.
Crowded place... hard to bock as it is, but you could accidently step on someones foot, and having an extra 4kgs or so press down would annoy anybody.
Take wider corners, Ive had it a few times when people are in that vegative shopping zombie like state and dont know whats going on only to bump into you on the turn of a corner.
Going into shops and whatnot, Ive found it to be more polite to take them off and then walk in (Ive got a Bock Lock now }:]) As, well, as any bocker knows, you cant stand still and I think its rude to not be on the same "level" as someone when you need to talk to them, let alone standing still as a curtosy.
Self awareness. Like when drivers slow down for horses and other "on" road animals, I found that people often said thank you when I simple stopped when ever they came by or up to you with a dog/child/pram etc. (Theres been a few times where Ive almost stepped on a dog and a few kids running around).
Also, In the interest of indesent exposure, keep your shirts on
