The LBS I used to use refused to run a booking in service because they were always busy. When told "leave it there, we'll get around to it in two weeks or so" I asked "what if I brought it back in two weeks, will you see it straight away?" "Now you are jumping the queue!" was his reply. So I went elsewhere and never went back. That LBS was extremely busy during the pandemic, but closed soon after when everyone stopped riding cheap bikes.
The LBS I moved to because it had a booking system was absolutely great in all respects. He responded to urgent stuff whenever he could but I didn't abuse it and used the booking system at all other times. However, I didn't think then and now, that they charge enough for the labour. I always refused his "freebies". For example, I took in my son-in-law's bike to sort out the rear brake calliper because I couldn't do anything with the stuck pistons. The LBS guy told me that not even his kit would shift them and he didn't have any callipers in stock to fit. He said "no charge because I didn't fix it. Where would I be if I kept charging for stuff I coudn't fix?" was his response. I insisted that he be paid for his time at least and he reluctantly agreed to take a tenner.
They too, were very busy during the pandemic. But about 18 months ago they halved their floor space and stopped stocking brand new bikes. Instead they concentrated on servicing and components. I told him one day that I was selling my emtb on eBay (when it was allowed), he offered to have his shop as the collection point and then the buyer could quiz him as to the genuine nature of the bike, while I was out of the shop. The sale went through along with some extras. The buyer told me that the ability to talk to the LBS was a clincher. I paid the LBS £50 for that service. I did it again for my grandson's bike, paying a similar proportional tip. It was a great service and I plan to use it again.
Two months ago my mate was in there and reported that the owner was looking and sounding depressed. A week or so later I called in just to say hello as I was passing, buy a magic link, whatever. But the shop was closed for the day "due to a family emergency". I haven't had cause to return so I am uncertain as to what's happening. I hope all is well. I do not want to lose this LBS "Newark Cycles" in Newark, UK
