You not sharing is your prerogative, and that's cool. However, if someone else was to turn up and use that spot; perhaps even "discover" it for themselves, I don't think you should feel any ill will towards them, right? I mean, it's a public space, and as long as they're being respectful, I don't see a problem with many people enjoying it. Sometimes good things get crowded, but that's the nature of public stuff - I don't think it's fair to claim public areas as your personal area just because you found it first.
