👉 The term 'turnstile tour' is a bit like describing something with no discernible end: nothing more than a ride without any real purpose.
An edgy example sentence might be: "Hey, I saw a 'turnstile tour' of some weird place in the city last night. It was so surreal that I couldn't get out until all the people left." This expression means something like "I went to an event or show where there were no exit points, so I spent the whole time trying to leave without realizing it had already been over." It's not actually a tour at all, just a description of a weird and surreal experience.
