While I fully agree with you, I would also fully expect the staff would do exactly nothing. They seem to have limited interest in their jobs to begin with and likely have no desire to get confrontational with the patrons over something that has zero impact on them. I rarely (if ever) have seen active supervision or management in a MLL or a Cafe. It's not like there seems to be anyone in a position of authority checking the quality of what's on offer, asking patrons how their experience has been, or even observing the staff, pretty sad actually.
