What function does the hotel lunch box have?

1. Now people need privacy, even public toilets have private rooms.

2. Improve the grade and make more money. In ancient China, there were elegant dining rooms. "Give you a silver or two and the dishes will be arranged."

3. Have a sense of security, for example, it looks cheap in the lobby, but when you finish checking out, you find that there are two or two pieces of silver missing.
