Went to BP to fill up my car as I had activated the Amex deal on it. Little did I know that even for a transaction under $100, I would need to enter my pin. Of course, I don't remember the pin on my Amex card, as my primary card is a Visa. Anyway, when I was trying to pay and the pin didn't work, I told the cashier please serve the person behind me while I sort this out. In the mean time a crazy lady was honking at my car and I went out to move my car to the waiting bay.
When I went in, the cashier told me that the guy behind me had paid for me. I was quite taken aback as I had cash in my pocket and I could even have paid from my Visa card.
Luckily, the guy still hadn't left the petrol station and I paid him the amount he paid for me and thanked him
My question is that have you ever been in a situation where someone tried to be kind even if you didn't need any help? I was quite upset with the whole chain of events. Anyway, that's just me.
TL;dr - someone paid for me at the petrol station. I didn't need any help.
I have had occasional small things like that. I would repay if possible, if not, I take the approach that is evidence of lots of good in the world and make sure I do something myself to 'pay it forward'.
