Can't speak to the rudeness, just want to comment on people leaving their bags on tables. We had a strict policy at Wisp against this and a complimentary bag check area. Staff responsible for bussing tables were instructed to remove bags on or below tables and bring them to bag check.
I think the Lincoln Base has something similar? Though I'm not certain it's manned. I do remember having a place to put my bag out of the way and free of charge. Ellen should have something similar.
Yes, only LP has the bag check program, not ME. I think that would go a long way to solving the problem.
