Usually the issue is the place is too small to handle the amount of business they have at peak periods. Another way of managing it is I have been warned in advance that I will be paired up if practicing alone and they run out of tables. Likewise, two players may be paired with not more than two more if they get busy. Seems reasonable but I can't remember when these policies haven't been self limiting, business goes elsewhere!
I have also seen them wanting to charge the entire group table time like two guys and two gals when only two are playing at a time or charging groups of as many as five full rates for individual players when all were on the same table. I retaliated by renting two or three tables breaking up the group before I went inside. Now we had three tables and were only playing on the middle one! Things got busy, people got upset seeing empty tables they couldn't rent, tough patoee! A few nights of this and the owner saw the value of setting a maximum price per table like the rest of the world and life was good!
In truth common sense needs to come into play. Owners need to work with players, players need to work with owners too. Being paired up can be annoying when you want to work on something but I have also met good people like that. Met some jerks that I plucked like chickens too!(grin)
