topless sunbather

A woman was staying at a hotel and she decided to go sunbathing on the hotel roof. When she laid down to sun her back, her bikini top fell off. She didn't care so much, though, because nobody ever came up to the roof anyway. Which is why she was surprised when she heard footsteps. It was the maitre'd from the restaurant.
"Ma'am," he said, "we were all wondering if you could put your top back on."

"Why? I'm not disturbing anybody."

"Ma'am. You're on the skylight."
