Yes Geoff, and they love you too.
Sometimes standards of service do differ across cultures. My favorite Chinese restaurant story:
In San Francisco many years ago, my girlfriend and I went to a play and after to a typical upscale Chinatown restaurant near Grant Street. I remember it was getting late, around 11pm or so (not late for Chinatown though). The restuarant was open and bright, we went in, ordered dinner, and waited. Dinner took awhile to arrive, and while we were waiting the lights in the restraurant started going off, and one of the workers brought out the vacuum cleaner and went to it, while we sat in the near darkness.
Eventually dinner came. Within five minutes, a guy came up, told us "We are closed" and made us leave. There was no point in causing a scene, so we left.
At the time we concluded that we must have offended them somehow (possibly due to the fact that I was a gweilo with an Asian GF). That may have had something to do with it, but now I just think that their mentality was simply "Hey, we close at 11pm. You want to come in and order it's your problem if we can't serve you in time for you to finish by then." It hasn't happened to me again since but wouldn't surprise me if it did.
