I'm pissed - Someone moved my bike

Little pebble under the valvestem cap gives them a flat tire without making them actually buy a new tire. Just sayin

Removing the valve stem cores with a $1 core tool from the parts store is even better, they have to go get new cores but no damage to the tires.

Why don't you just go and ask them why they moved it and tell them not to not touch your property again? Theft isn't it? Even though they 'returned' the bike it wasn't in it's original place. You don't have to be aggressive about it when you confront them - you can be the bigger man

I would be pissed to but I wouldn't risk getting caught for criminal damage by slashing their tyres or anything. Even though they were WRONG, sounds like they were careful about your bike. If you retaliate, you'll get in trouble - it always happens that way .............
