If you know, just say so... click on comments.
I don't know who guessed because they posted as anonymous... the picture was taken in Florida, near Seminole.
In my 20 years of living in Libya and my 27 years of being married to a Libyan, and the two years we were engaged... That's a lot of years! And a lot of chances to get to know the Libyan mentality and culture.
One of the things that I found surprising came about while I was visiting a Libyan woman who was potty training her toddler. Anyone that has any experience with that knows that you spend a lot of time standing next to a kid that is sitting on a toilet. But to my surprise this woman had her child standing on the seat, legs wide apart, squatting. When I asked her why on earth she was having the child stand on the seat she looked at me strangely and said that this was how she had been taught. I asked if she still stood on the seat and she said 'Of course.' Later I found that this was not uncommon among Libyans who were used to using Turkish style 'hole in the floor' toilets. I often find foot prints on the seat of bathrooms I've been in in Libya. I probably would have just thought the seat was dirty but ever since seeing that kid standing there I look for footprints... lolol...and wonder why on earth they can't figure out that you are supposed to sit on the seat, not stand on it.
While I was in the US my sister took me to have a pedicure. Knowing that I'd be sitting for a while I decided to visit the bathroom first. It was located in the back of the salon and was used mainly by the staff, all of whom were Vietnamese. I sometimes wonder if the entire female population of Vietnamese in the US are working as manicurists. Anyway, I walked into the door and was confronted by the sign. I read it and started to laugh and decided I'd better take a picture because no one would believe me.
I don't think I've ever heard of an American standing on a toilet seat. Standing on the toilet seat must be a third world kind of thing. The sign was posted for the Vietnamese employees.
Culture even finds it's way into the bathroom...lolol
A commenter pointed out Baba Gannouj's blog. He posted this image of a sign from Syria:
