The top floor sign says
BEER CAR WASH
Anyone? Want to have your car washed using beer?
Actually, if you come to this shop in my office, the bottom shop (which you can see the word Car Wash there) washes cars. The shop on top with the sign which is blurred as the sign is too bright is actually a pub. Both shops have the same owner. So, the shop's window on the 3rd floor which can be seen quite afar, in order to attract customers has the sign "BEER" which has an arrow on its left pointing up and "CAR WASH" which has an arrow pointing down.
And you get that nonsensical sign which is kind of a great idea too? If Singapore can have their topless car wash, we wash ours with beer....
