This is always one of those issues that good people can agree to disagree about agreeably. I see both sides of the argument but I’m inclined to fall on the side of if I’m paying for the use of chairs I should be allowed to bring my own drinks but when chairs are provided free, absolutely you should NOT bring drinks or food. Truth is, we don’t very often bring food to any beach although we might bring water or na beer which no one on the island seems to sell but once I’ve paid for that chair, I believe the choice should be mine to make.
