If the model is worth watching the model is worth tipping.
Not always, I've watched in horrified fascination as feet, bats, bedposts, cellphones, microphones and once even a keyboard were inserted into vaginas and have never felt the urge to tip. Then again it wasn't something I had intended to watch, or would pay to see, and certainly wasn't turning me on.
There's no requirement to tip something you're rubbernecking in passing - it's in public, it's like stopping for a moment to listen to a busker and then move on. If you continue to go back there you should probably tip...I dunno, now we get back to the whole "am I a freeloader if I'm sitting in public chat not requesting anything, and chatting" debate. Bottom of the line though - tips are voluntary, if you're not in a group or private show you're not obliged to tip (and the model isn't obliged to allow you in her room either). I guess that's between the model and the member.
