Take boys to barbers, I am wearing jeans, they are calling me "Dad". They have haircuts @ £4.50 each. Loads of hair on the floor as they are reluctant visitors to the barber. I have a haircut £5.50 (not so much hair of the floor ~ I say this is because it is white and you can't see it, they say it's because there isn't much to cut these days).
I go to same barbers on my own (as I tend to visit twice to their once), not wearing jeans and I get charged £4.50 PENSIONERS RATE

Not sure whether to be pleased at saving a quid or pissed off at being aged up by three years.
I have stopped tipping her now 'cos if I were a pensioner I could not afford to and, as I am not a pensioner, she deserves no tip for guessing wrongly about my age.
