Thing is they know you. Never been a big LBS visitor, mainly as I do all my own servicing - may pop into the odd shop. I've had two 'hellos' from Rick Greens via John The Monkey when we did bike to work, and one from another colleague last week..... you can't hide, and I haven't been in that shop for a long time - although they have, in the past done a few pairs of rather nice wheels for me......and other stuff.... (plus I used to race against Paul)........
My other LBS has known me from my teens - I grew up racing with him (and he is younger than me) - TBH, he was a class above most of the club riders - Commonwealth Games etc..... Anyway, he was the fella that sorted out my new fixed...
