A few weeks ago I was in Subway (surprise surprise!) & there was a student behind me who could only afford part of his sarnie. After hearing him ask the guy behind the till what he could do & only getting grunts back I decided to jump on the 'act of random kindness' bandwagon & help the guy by paying the difference. He was really chuffed & I felt really good!
I didn't think much more of it till last night when I pulled into a carpark & someone came over & gave me their pay&display ticket for the rest of the night! Which was ace cos it turned out I didn't actually have enough money anyway!
Gotta love a bit of karma!
