Went to the petrol station to top up the air in my car's tyres this afternoon.
I'm overly concious about this issue now as I went through a period of not checking the tyres at all, resulting in them quickly wearing down to well past the legal limit. Not big and not clever.
I went to a Texaco petrol station close to where I live. I pulled up beside the machine and then - being the precise keeno that I am - went around my tyres checking what pressure I should be filling up to.
Again, in my days of laxness, even when I did get around to filling air up, I'd just fill up without checking anything. I must have often filled up the car with the air that the push-bike in front had used. This probably was a secondary factor to the tyres going bald.
Anyway, as I was being safety concious and checking the tyres, a man pulled up behind me and asked if he could jump in. I was just about to begin the process myself but he had greasy hands (like a mechanic) and looked bigger than me so I let him cut in front.
However, when he was done, he politely turned round and, with a cheeky little glint in his eye, said that there was still quite a bit of time left in the machine and that I was welcome to quickly make the most of it.
Our mechanic friend must have put at least a quid in. It's good to know that polite people still exist.
