The shop I deal with has 2 mechanics. One is the manager and been in the business for 25+ years. The other is in his late 60s and has been in the business longer than dirt.
Now the new Trek store has 4 "kids" that didn't know my 2015 Emonda SLR was made by Trek. And when I asked the mechanic a question about my Bontrager floor pump, he said he never used one. At lease they have a clean bathroom and water bottle refill station.
