What do you think?
If you are at a bar/arcade/show and a game is noticeably un-level, is it OK to crawl under the game and try to level it out yourself?
I have done this a few times at our local arcade, and never saw the harm in it. But recently I witnessed someone do this, and another league member went on for a while about how you should never "adjust" someone else's machine. It was debated for a while and would like to hear others' opinions on the subject.
