A few things:
The most memorable restaurant service I’ve ever had was at a Steak and Ale restaurant some years ago. I was single, eating by myself, and reading a book. Usually when I’d do this, I’d either be ignored, or checked on so often that I couldn’t read my book. The server I had that night was almost psychic in the way he came by only when I was at a stopping point. He was just attentive enough, didn’t interrupt me, was there when I needed something. Years later, I still measure all my dining out experiences against the gold standard of this one. I tipped him hugely, and sought out the manager before I left to tell him what a wonderful eating experience I’d had.
Not long ago, I went to Publix to get some vanilla. I went to the spice aisle and picked out a bottle and went to checkout. The cashier saw my purchase, and asked if I’d seen a different brand that was a larger size AND cheaper than the bottle I was buying. I said, no, I hadn’t. She ran over to the display (not far away) and brought it back to me. Of course, I bought it, and on my way out of the store, I found a manager and told her how helpful the cashier had been, and how happy I was that I’d stopped by there that day.
I bought a folk harp a few years ago. It’s a 34-string diatonic harp (not one of the big orchestra harps) with levers on every string. But some of the levers hadn’t been mounted correctly, so that when you engaged the lever (to sharp the string by a half-step) the string would then be out of tune. After living with this for a few years, I thought about asking a local harp-builder if there was anything he could do about it. He took in my harp, re-regulated the levers (including re-drilling some of the holes where the levers were mounted.) What he charged me? $10, I think.
Recently, I had a problem with an HP digital camera we’d bought last year (it was still under warranty). I went through the tech chat line on the HP site and they determined I had a problem that they couldn’t resolve through the line. They sent me out another camera, with instructions to pack the old one in the box the new one came in, and send it back in. I thought that was pretty neat too.
There’s good, cheerful service out there. Sometimes it’s hard to find, but it’s there.
