My local National Tyres (Kingston) was pretty good when I got new tyres about 2-3 years ago, took good care of the alloys, nicely hidden weights etc. However, last year I needed new rears before an MOT, I'd arranged for them to get Yoko AD08Rs in the right size and after I was told they'd arrived turned up on the morning of the MOT to get them fitted. It was only when he was half way through fitting the second tyre I had a look at realised he was fitting some budget (ish) Yokos!! I pointed it out and they said they didn't have the AD08s and what I wanted to do. To be fair to them, they didn't actually complain or try to charge me for the time fitting both the wrong and my original tyres... but still.
