Yup. This sounds like a pretty objective, truthful review of a typical theatre from yesteryear. Few people went to such places to meet their husbands, create LTR or even start a romance. Sure, such things must have happened, too. But this was really no one's original intention.
You cruised because you wanted to get your rocks off. If you chose a working day, chances were that the place would not be too full, but that the guys there meant business.
Cruising is a bit of sport, too. No one really scores all the time, every time, and there is always a real chance that you may be wasting your time and money.
To some, a major upside of such venues was that they were meant to be maintaining anonymity. The blow & go, fuck & go, or whatever you may be after, is always ALL and EVERYTHING they wanted. You did not want to meet a dude at the bucks, get to know him, listen to his story, and answer his questions before you hit the home run.
I am probably a bit old fashioned here, but I'd always hit a theatre/club/bar or spa have a look around, and try to hook up there with someone whom I find attractive than spend time "chatting" on Grindr, coping with old pictures, fakes and flakes, trying to sync his schedule with mine.
WYSIWYG right there and then. So, you call your shots, and score or not. The life moves on, and so do you
