What are some special features/traits of Yum Cha?!

Here's some customs that I think stand out:

- It's customary to pour tea for others before doing it for yourself.
- Instead of thanking the person for the tea, two fingers tapped against the table suffices as a means of saying "thanks."
- A tipped or open teapot lid signals a server to come to refill the pot with more hot water.
- It's common for two (or more) families to share a table during lunchtime when a restaurant is crowded.
- It is deemed very hospitable to pay for the meal - in fact, most people fight over who gets to pay the bill!
- It's not unusual for customers to eat "lunch" early in the morning (better to avoid the crowds during the afternoon).
- Food is served in the center of the table (family-style) for everyone to enjoy a little bit of everything.

Yum Cha literally means drinking tea. Cha - in Chinese literally means - tea! But, unlike the English Tea Time, the treats usually comes in the form of small, steamed or fried dumplings with either sweet or savory fillings called - dim sum. Modern treats have evolved into noodles and desserts and anything that the particular restaurant want to serve. The timing of Yum Cha also varies. It can be served during breakfast, lunch or dinner.
