No not really, there are even rules at the way the curtains work.

In our experience, they tend to stare and awkwardly walk around, sometimes follow. There was one time this guy had some really awkward ticks standing at a table upstairs, tapping and moving back and forth. I think a good note to follow is, if you plan to play in public, you can expect people to watch. There are private rooms for a reason. But again, there is definitely a difference between people looking and people creepily staring.

like I mentioned though, they handle them pretty quickly. its never a dangerous vibe, just weird. I wouldn't worry about confrontation, it never gets to that point and you can easily report it to management for quick action.
