When you buy 2 seats on an airplane, you get to use those two seats and nobody else. When you charter the whole damn plane,nobody else gets on.
This guy bought to tickets to any two spots on that parking lot and he should be able to use those two spots in any way he sees fit as long as it doesn't violate some law or regulation. Would it be wrong for him to put a bed on that exact same spot? I don't think so, as long as he clears the spot before the tickets expire.
Do you think I am wrong? Show me the law or regulation that says you can't rent two spaces for one car.
