We had two rangers in the party, mine and another player's. I built mine to be sneaky and had around a 14 point bonus to stealth checks; he built his as a fighter and had a massive penalty to stealth checks.
Any time I tried to sneak up on people, he would do the same. I would make my stealth check, but as he had penalties and therefore didn't, we were both always spotted. We were spotted because he said every time that he was following my character, pretty much right next to him. This was after numerous attempts to let him know that this was a bad idea. This happened almost every week until the player left the game. Nobody misses his character.
