Does anybody have a grasp of this concept? Have you eaten here and felt comfortable when they came to your table? The whole thing puzzles me a bit. I had two come over while dining, and wasn't sure how to react, whether this was some type of show - or hustle - or just a weird novelty. Didn't know if I was supposed to tip them, either, but I've read on YELP that some of them have expected cocktails and be invited to eat with them. This is a real head-scratcher.
