Dealing with obvious colusion at the table?

[Teetster]

I went up to Seneca Niagara again last night. The room was as busy as I've ever seen it, I think all 25 tables were running and the wait list was 20+ deep for some games.

Anyways, I played some O/8 until my normal 2/5 NL game came up. I sat and it became immediately obvious that the 3,4 and 8 seats all knew each other. In fact they refered to themselves as "partners". I was like OK, whatever.

Well, it became a problem pretty fast. They shared the same bankroll. They would pass chips back and forth regularly. They would raise and reraise to get others out of pots and then check down. It was pretty sick. '

It didn't help that for the previous 2 hours before this, I hadn't won a single pot. After almost 2 hours with these guys and their antics and I had it. I was going to find a floor. I got up for a bathroom break and was going to talk to someone, but when I came back the "partners" had decided to leave. They were probably up over a grand.

What the hell do you do in situations like this? If I call the floor to the table, I look like a total nit and piss off everyone. If I don't I'm essentially playing at a huge disadvantage. I mean, it wouldn't surprise me if these guys had a signal system worked out.
