Exactly. Why don't you tell us the property?

Unlike many of the live-n-let-livers here, I think that *is* something to be angry about. The $ you pay for a hotel is not just for the room; if that were true, it would be a Motel. You also pay for the common amenities, one of which is the lobby and entryway, which should be attractive and functional and not generally populated by couch-sleepers.

You should lodge a complaint and press the angle that you are nervous for your safety with non-guests allowed to sleep in the lobby....
