I use the same mentality when dealing with the local hardware store. I told them many years ago that they were my first stop, always. If they didn't have it or couldn't get it within a reasonable price and time frame, then I'd look elsewhere. I stay true to that committment.
Bought a two pack of halogen bulbs for my stairway lights. One burned out two weeks later. They would replace it, but they're only sold in twin packs. They gave me the twin pack without charge even though I agreed to pay half price to get the 2nd bulb. I wanted to convert more of my Christmas lights to LED this year. Reels were marked $25 each - I have 5 reels. Teller asks a co-worker "are these being marked down tomorrow?" Co-worker checks, returns and says "Yeah - he said to knock $10 off each reel for Tom."
So yes, you take care of me, my business will faithfully return - AND I'll steer everyone I can your direction.
You decide my business isn't valuable, then I guess it won't be. Like the GM dealer that "harumphed" me when I tried to explain the pratfalls to avoid replacing my water pump and screwed it up anyway. I don't bad-mouth him voluntarily but if someone asks I tell them I wouldn't take a bicycle to them to work on. The GM dealer that worked with me through the cat converter saga? I'd go back to them in a heartbeat. They went out of their way to get us in contact with GM directly when the cat wasn't available, got us into a rental pronto, continued to communicate with us while we waited for the part and when GM seemed to balk on covering the rental they adamantly said they would address it with GM and they did.
