different greeting ways indifferent country

I am a foodie and I was lucky to met a friend who wants to eat outside with me.It's interesting to eat in different kinds of restaurants and experience different greetings,so I wondered how people greeting with each other in a restaurant. There are moments that we need to eat outside for entertain or relax,and we want to enjoy the leisure time with our friends,so we go to a restaurant to eat.we enter the restaurant, the waiter greet us with"how's your day"or "how can I help you"to start the conversation ,they usually smiling and give us an eye contact,nodding their head to show respect.We appreciate the waiter's body language and the neat cloth and clean hand ,we decide to eat here and the food taste good ,after we finished eating,we will give some tip for the service.
That's the situation we will face ,however, things will change through the size and location the restaurant is.The difficulty is that we talk about restaurant but we have variety of  situations,we need to find the common phrases.However, we enjoy share different greeting ways in our own country.
In China ,we usually use two kinds of phrases"Have you ordered yet"and "How many people do you have",I guess maybe we have a large amount of population and the restaurant usually very busy,they need to make full use of the space to make big money.In Guangdong, besides this two greetings,they will ask"which kind of tea do you prefer",Cantonese love drinking tea while eating,and the first cup of tea is for you to wash the dishes and chopsticks you will use later,and the younger generation or host will do it for the elder or guests. The first tea usually called wash the tea to get rid of dirty and then you enjoy the second ones. Considering this situation ,we usually need to pay the tea fee in our bills,usually one dollar per person.In Japan,Rina said they usually ask"Do you smoke or not" because they have smoking room for people who smoke,It's very different from China,because in China, it's impolite to smoke among people, we usually have areas for smoking but not on the table.
During this research, we find that every little thing can have a big meaning if you are eager to find the deep significant of it.

Something About the Presentation

I was in group one and our topic is"How to greet people in different countries" and Rina is my partner.

There are several reasons to choose the first one to give this presentation . Firstly,I am a person who don’t want to worry about something for a long time, as a saying goes ” It’s better to suffer short-term pain rather than long-term torture”. Second, I do think that we will do a great job in a short time. However, after we finished the speech and heard other’s work, I don’t think it anymore. 

We have advantages and disadvantages.The advantage is that we do the speech fluently and didn't use the mention card.And disadvantages are much more than advantages.Our presentation is simple and short,and we didn't have attractive pictures which looked a little boring.At the same time, compared with other groups, we only chose two different countries( China and Japan), we should find more to strengthen our talk and make things clearly to understand.If I need to score our presentation,I will give only seven points.All in all ,we still have space to improve.

During this week's presentation ,I learned different cultures and unique lifestyles about food, clothes, weeding ceremony and traditional festivals in Korea, China,Japan and American(Hawaii). And if we have time, we will have a lot of interesting things to share with each other,because culture is defined as the social behavior and norms found in human societies and we still have much to talk.Through this way, we can learn language with a high interest which will help us better understanding each country.
