Cultural mores.

We have quite a lot of Japanese and Chinese in this area, attracted initially by the Foundation but many stay to make new lives for themselves. I'm ashamed to say I have trouble telling the difference between the nationalities. Just when I think I have it down the person in front of me turns out to be Korean. What they all have in common are excellent manners and the habit of bowing whenever they feel they have been given a service. After a customer has bowed their thanks to me I feel I want to bow back, so often do. Then I find myself bowing to the next customer who is probably local and thinks I have taken leave of my senses.
