Diners at a California Mexican restaurant had an unexpected guest when a woman came crashing through the ceiling. The restaurant said the woman asked to use the bathroom and an employee obliged. She went into the bathroom and was there for a long time, causing a line to form. A short while later, she broke through one of the ceiling tiles and fell to the ground. Police said the woman was homeless and appeared to be on drugs. She told them she didn’t remember how she got into the space above the ceiling.
