My part time job

I have a part time job. I work in a Japanese restaurant. I can learn the many manners there. For example, how to behavior in a tatami-room, make shochu, speak to guests and so on. Shochu is Japanese liquor. I don't know almost manners. So I often fail. I was advised by a mistress, today too. I held out a dish to a guest from left behind by my right hand. It is wrong. When I hold out a dish from left behind, I have to use my left hand. The reason is clear. You will be able to understand if you image the situation as a guest. If a waiter hold out a dish from left behind by right hand, you will have to avoid to right. My working place's dinner is a full course. So if I hold out dishes by the wrong ways every time, the guest have to avoid me every time the dish come and may feel nasty. I have to care. A converse case is same. When I hold out from right behind, I have to use my right hand. I have been having this part time job. I wish that many guests who I have served didn't feel nasty by this wrong service. (210words)
