Turn Left At The Bridge

We went shopping this afternoon - not our usual big once-a-week shop, but (for long and boring reasons) our second mini-shop of the week.
Now, when we’re going around the supermarket filling up the trolley, I know pretty well how much we’re spending. I don’t know the exact price of every item, but I can estimate it and keep a running total. When we reach the checkout, my estimate invariably comes to less than +/- two quid of the total.
Well, that’s how it used to be. This afternoon, we went around the Co-op with me doing my usual running price estimation. At the checkout, I was shocked to find that I was charged more than a fiver over my estimate. It could have been quite embarrassing, as I was left with only about 50p in my purse. Naturally, I checked the receipt, but all was as it should be - it was just that stuff was costing more.
With our weekly shopping bill going up by a tenner, and fuel costing so much more as well (we’re 15 miles from the supermarket, so we have to use the car), things are going to get rather tight for us.
Oh bum….. We’ll just have to try to earn more money….
