Interestingly my late father in law was a mobility officer to the blind and he would have said that if anyone was going to find this funny it would be blind people, but maybe humour is now defunct due to political correctness in many countries.
This is not a criticism of anyone rather the mantra that we must all bow to the altar of political correctness and are no longer entitled to our own opinions, sense of humour, or faith, unless it permits that which is only politically correct.
A sad day when all we can see, if of course I am allowed to say that, is zero tolerance for anything that doesn't fit in the PC box.
I am surprised that there wasn't a similar angry response to the braille on the car manual gear change.... which was also funny and perhaps more of a jibe at PC'ness.....
I will just go and put on my nomex..... (which is a flame retardent oversuit and not an anti Mexican sentiment).....
