This bus STOP button is (as you will see if you peer closely) upside down, which means the braille symbol embossed on it is upside down. My blind daughter hardly uses braille now, but still it irritated me! She would probably laugh at it though because she's not a pedant!
True NotSpaghetti but my daughter would still enjoy it! My braille is very rusty (I'm not blind but learnt it with her) but I think the upside down symbol on the bus is the equivalent of a { or }. (At least the spoken 'next stop' messages aren't played in reverse. )
