Most LBS mechanics standards will vary. I was not that impressed with mine when I bought my last bike.
e.g. Bar tape put on badly, handlebars on at unusable angle (whilst on drops any jolt and my hands were slipping off), hoods far to far forward to be comfortable, front derailleur cable routed wrongly into derailleur clamp.
I did my own 6 week tweek job and corrected problems. Moving the levers meant taking bar tape off when I found that the angled cut at the end was so ragged it may have been cut with nail scissors/clippers.
Boardman I bought from Halfords, a few years ago, was set up perfectly. I've hardly had to do anything except twist the barrel adjusters.
I'm not going to name my LBS on line but I won;t use them again.
