I think it's polite. What is politeness for? Standing?

There are many kinds of etiquette, and the things that need to be done are different. There are banquet etiquette, exhibition etiquette, sales etiquette and so on.

I've done all three. Banquet and exhibition etiquette is a little simpler, generally standing in some places, such as gates, halls, aisles and so on. Used for decoration and guiding guests. In addition, banquet etiquette should include serving, pouring wine and cutting the ribbon for exhibition etiquette. Sales etiquette, in addition to introducing products to individual customers like promoters, but also showing the performance and characteristics of products in public with products, according to sales performance commission.

In a word, it is not easy to do good manners. Besides standing for a long time, you should be familiar with various etiquette norms, and it is best to know a foreign language.
