What to say? Three consecutive days of going to the toilet can not live in peace, just want to vent well, can't you? Because the door of the factory toilet last time did not have an iron latch, these two days have chosen the toilet door with iron latch, but back to the door there are people to pull open the door, my God! Dozens of rows of toilets, is that not enough? How many pits do you have to pull, obviously closed the door, so simple and easy to understand the reason I understand, that is to say, the toilet is someone, you open the door for what?
