The last thing I needed

The last thing I needed when I have this bad shoulder is to slip on some wet tiles. I was down at a chip shop picking up some invoices and the lassie was outside cleaning the tiles. I stretched my foot to avoid stepping twice on the tiles and slipped. The chip shop owner looked up at that point to see me in pain. If I lived in the USA I'd have sued him. I didn't fall or anything like that - it's just that I can do without sudden movements.
