once I was late for an important meetup as I'd been swimming with my cousins at the pool and lost track of time, I was running to the bus stop which would have got me there but about 30 minutes late with a good chance the person i was meeting having left by then and this being pre-mobile era for most people no way of letting them know.
out of the corner of my eye i saw a flash of purple so turned around and saw it was a £20. this meant i could get a taxi and be there bang on time, so i went into a shop to treat myself to a can of coke and some sweets on the way to the cab rank.
I arrive on time, pay the taxi and meet the person as planned, I proceed to tell them about my excellent luck and reach in my pocket to find the remaining tenner from my haul only to realise it had fallen out of my pocket in the taxi.
a better man than I might have seen this as the universe making sure I got what i needed to be where i was supposed to be. personally I'm still fucking livid that I lost a tenner 26 odd years later.
