Is it me or is it actually becoming more difficult to find free air...the convertible has been sitting around for a couple of weeks and one of the tyres suffers from a slow puncture. So considering it was being used today, I thought I would check it. All the garages around me have the digital pumps that requires a minimum spend of 50p. Because two of the tyres had recently been replaced and the others were checked at the same time, I went to Asda where they had a conventional press and hold system. The problem is that's now been replaced by a digital unit and they want a minimum of 20p spend! if only could use the air we breath...for free...or is it?!
