A blind man was selling matches outside the railway station.
"Matches 10p, get your matches only 10p"
A commuter handed the man a 10p but didn't take the matches.
"Excuse me sir, you forgot your matches"
Commuter replies "Forget it, I don't smoke"
"Thank you kind sir"
This went on for weeks until, one day, the blind man grabbed the commuter by the arm and asked...
"Excuse me sir, are you the kind gentleman that always gives me 10p but never takes the matches?"
"As a matter of fact, I am"
"Well they've just gone up to 12p"
