Is this allowed in "real" casinos

[PokerintheI]

I've never seen that allowed in a casino. Verbally discussing such an agreement "is" collusion. Although I see players attempt it all the time. In unregulated games I know it is a bit more common, and since they make their own rules, not much to do about it.

I would not immediately leave a juicy table due to this, but I would keep an eye out. If it looks like two raise-monkeys are going to continue doing this on a frequent basis, I would rack up an leave, but otherwise I would just chalk it up as a cost of playing a good game. (sort of like tolerating the drunk or smelly or obnoxiously talkative guy)
