I had a similar experience from a bike shop in central London. Condor couldn’t fit me in in time so I went a few doors down the road. I went asking for a service to make sure that everything was clean and running smoothly as I was due to ride 120 miles a few days later on it. Ticked the bit on the form asking to be contacted should anything have worn out and need replacing.
The service was below
Frame & Forks
* Wiped down and checked for alignment
Wheels
* Hubs and rims checked for damage and wear
* Bearings checked for free movement and adjusted (if applicable)
* Wheels trued and spokes retensioned
Tyres
* Tyres and sidewalls checked for wear and inflated to correct pressure
Headset
* Checked for free movement and adjusted as necessary
Bottom Bracket
* Checked for free movement and adjusted as necessary
Bolts
* Checked and tightened to correct torque
Drive Train (chain and cassette/block)
* Removed, cleaned, checked for wear and re-lubricated
Brakes
* Checked for effective operation and adjusted
so I was a bit annoyed when I collected it to find that they had replaced the cables for the brakes and the pads, and adjusted the front brakes to the point where the wheel would not spin as the wheel was just out of true. I was told that the wobble in the wheel was actually in the tyre so it was not part of their service, and that I would have to pay for the parts I hadn’t asked for. The headset was also adjusted so turning was difficult, but they didnt think it needed replacing
I refused and eventually got out with my bike adjusted back to where it was before I took it in having agreed to pay for most of the service.
That was the last time I went into one of their shops and would not recomend them to others
