In fact, when I go to a club, especially clubs like the Wind Mill with many areas, nooks and crannies, and two different floors, I do consider myself entitled to go in, see the atmosphere, and decide whether to stay or I don't like it and prefer to leave.
Given the drop in the level of clubs lately and the lack of atmosphere in many, I can try several clubs until I find one I like, sit down, order a drink and stay a while.
I certainly don't consider myself obligated to stay in a club if when I enter I don't like what I see.
