They might say that it's within someone's right to do that, but you should complain anyway.

Especially if you are playing 2/4. They seem to have lightning tables at 3/6 and above, and you know if they had lightning tables at 2/4 that's probally where most people would play (which would be everyone since there is usually only 1 or 2 tables running in 2/4), which would eliminate this particular annoyance.
