My family and a large group of our friends made our 3rd annual trip to Montauk (I know, not exactly the Hamptons) and observed some less than considerate behavior.
We were staying at the Royal Atlantic and watched a group of roughly 15 people pick up hotel lounge chairs, and like a well orchestrated army of ants, transport them down to the beach on their backs, in their arms , etc.
As they clogged up the entrance to the beach they could be heard commenting, "We're probably not supposed to bring these down to the beach but I saw some down here yesterday and they were back by the pool this morning."
Later on, and as I expected, most of the group marched back up to the hotel and left their Great Wall of Chairs on the beach. While a few members of the group lingered on the beach nearby, they watched two staff members make about 15 trips back and forth to the beach in 90 degree plus heat and humidity (as told to me by one of the women in my group that happened to be on her balcony overlooking the beach).
