This reminds me of a visit to Anguilla off a cruise line. Before we arrived at the landing we arranged for a driver to pick us up and take us to the beach. We asked where he would recommend. He said he would take his to his "friends" beach shack and we would be cared for nicely. ( I can't recall which one) He drove us there and walked us in to introduce us. I asked how much for the chairs. Answer: "Nothing, as long as you hang around eat, drink here and behave". No problem

We had a great time. Then we noticed some some cruise folks show up and just start grabbing chairs. Owner was on then immediately and was charging 10 bucks per chair. No exceptions.

Other pro tip: Our cruise ship towels were white. No logo. Their's were had the their cruise lines logo all over them.
