After the main shop I went over to the kiosk to get my mobile topped up, buy some stamps and to get £50 cash as I was paying by card.
I had a brief conversation with the lady on the till about stamps as it happened, (No, don't ask; I know it's boring!) which was probably just as well because she remembered me instantly when I went back an hour later.
Why did I go back I hear you wondering aloud, but, patience... we're now getting to the exciting part!
Back home, I took all the shopping out of the car boot and then I took next door's cat out of the boot, as he had sneaked in while I wasn't looking, put all the shopping away and then looked in my purse for my receipts.
And that is when I suddenly thought, "Hells bells!!!"
The reason for this was the distinct absence of £50 in said purse. Nothing, nada, niente. So, back to Sainsbury's, taking corners on two wheels, of course (See, told you this was the exciting part.) and skidding to a halt in the carpark before racing (well, striding purposefully then) into Sainsbury's and back to my new friend on the till who apologised profusely before handing over the dough.
After that, I skipped happily back to my car and went off to B&Q to buy two more large sacks of compost which I manhandled all by myself.
The brain might be going but the muscles are still in good working order.
