So I needed a battery for Notrun and I had an hour to spare before a flying lesson, so I wandered over to Flitwick, blagged a cuppa from Pip, then trotted up to see his tame auto factor. They couldn't find the exact battery in stock, but they had one that's a tad wider. The chap in question then went away and came back wincing. "Sorry guv, that's 55 notes!". Ouch. Fucking Chinese. Ah well. "Can I bring it back if it doesn't fit?". "Oh yeah, no problem. Tell you what, give me a phone number and a card number and take it. Give me a bell if it fits and we'll charge the card." Blimey. The chap's entirely happy for me to wander away with the battery and bill me later. So I did. I got about a mile away on the way home when they called. "Come back!". So I did. They'd found a battery that was an exact replacement. And it was 27 quid. A saving of 28 of your Earth pounds. Top Gear in Flitwick. Hugely recommended.
