Blowjob Bars Question

I am really interested in these blowjob bars. I only really have a few minor questions. I have tried doing some research, but I can’t find solid answers.

What blowjob bars in pattaya actually allow guest to just get a blowjob at the bar?
I’m really liking this idea of just getting my dick sucked at the bar while I’m smoking a cigarette and drinking a beer.
Which ones don’t make you go upstairs to some private room?

Also, is smoking even allowed at these places?

Here is my other question.

Can I just get blowjob after blowjob at these places?
I want to spend about 4-5 hours at one of these places so is that possible?
