Today when I ordered my coffee the server filled my mug with boiling water, dumped it and then hand dried it.  I used it to warm my hands before I filled it from one of their hotpots. It was a little thing but it gave me a warm-fuzzy. It's the same with those old fashioned milkshakes. They're mixed in those frosty stainless containers and there's always enough leftover for one happy refill. You might call it a cold-fuzzy but the point's the same - it's the little unexpected pleasantnesses that separate the good from the great.
