You know the type of people I'm talking about. The ones who sit at a machine but also play the two machines on either side of them (then yell at you if you try to sit down and play).
There also also the ones who have a friend sit next to them. The friend drops in a coin every 5 minutes or so to keep the illusion that they're playing but otherwise just takes up a machine.

These people are no big deal until a casino starts to get crowded.

Anybody have any stories about slot hogs or tips on how to deal with them?
