Well, if done at a public beach IN THE WEST, fine, as people who do not want to see it can move on, and most people don't care anyway. Doing it at a compound pool in the ME is, IMHO, not appropriate, as there may be people who consider this, for different reasons (for example, adolesnts, small children )inappropriate. One should be considerate. And having a bit of a tan line, well, not a big deal considering one can be in the sun by the pool at lot more than in the West.
Plus, is it really nice to be leeched at?
