There "was" a small chain of dive shops in NJ that had that attitude. The father had built the business and the kids didn’t want to be bothered ordering stuff even if I gave them plenty of lead time to include it in a stock order so I stopped buying from them.
They broke an SPG on a reg that was in for service and didn’t even offer me a deal on one they had in stock so I stopped using them for service.
Then they got lazy changing the filters on the compressor and I stopped going there for fills or anything else.
