If I feel rushed, I have no qalms about asking the server or the manager "are you in a hurry to have this table?" If I'm loitering after the meal and it's clear that the establishment stands a chance to "turn the table", then I understand if they ask me to retire to the bar or something of that ilk. But don't rush four courses of a meal just to give yourself the chance to turn the table. I'm a paying guest and I deserve to eat at a reasonable pace. Rush me and only bad things can happen. I will likely start by complaining, then I may reduce the tip if I feel the waitperson's doing the rushing, and finally, I may never return and I am likely to bad mouth the place to every person I encounter afterwards.
