there's no point to vigilante faux theft, unless you want to risk that person walking out to see you messing with they're QR wheel, and then have them u-lock smash your jaw into 20+ pieces. imagine trying to talk you're way outta that one, "but i was a trying to teach a lesson by removing you're wheel, don't you get it you idiot! *clank* *crunch*"..leave the theft and lesson teaching to the crackheads and bums, and if you're really irked then a passive-aggressive note would a better avenue. don't mess with other peoples stuff, thats negative points
