I try to avoid my main LBS – not out of spite, but they have just been a bit naff in the past.
They liked to over-promise on when things could be done by and I have made at least two trips there to pick up my bike as arranged only to find lots of apologies, muffled shouting from the back of the workshop and “if you just want to walk into town and get a coffee I’m sure we can have it ready for when you get back” type comments.
They also installed a Hope Headset for me, used a star nut then put the expander plug in their spares drawer (might have been incompetence, might have been nefarious) – I had to ask for it back in any case.
They’re not a bad bunch, but they’re not brilliant either and getting a few tools together and doing it myself has been far easier (in most cases) than taking it to the ‘professionals’. And it has helped me to understand how things work etc.
