After 2 days of Medical Leave, I come to work today (My MC is 3 days, I wasted one day). The whole morning I feel sleepy, luckily I’m not the one who driving the car (My colleague is the one who drove the car), I sit beside the driver, I felt sleep. I reached company around 07:30am and I clock in then I went to toilet. When I push open the toilet door, I saw a girl stand inside the toilet and she looks at me while I walk in, then I’m shock (2 days MC, male WC changed to Female WC?), I walk out from the toilet and looks at the signboard, it shows male WC (OMG, why there is a female inside there?). I told her “ This is male toilet, why you are here?”, she immediately walk out from the toilet, but I sense there is one more girl inside the toilet room. Few minute later, a girl walks out from the toilet.

Why they can enter to the wrong toilet? Isn’t the toilet signboard is a universal type? Please see the signboard below by yourself.
For the left hand side is female and the right hand side is male.

By this, it chase away all my sleepiness~
