While dining in a restaurant, four people came next to us.
Judging from their clothes, they should be Hong Kong people.
In fact, there is nothing to say, but the four of them are quite strange, and I noticed them.
What is it then? After they sat down, they took out their hand sanitizer/Isopropyl Alcohol, sprayed it on their hands and kept rubbing.
The most surprising thing is that hand sanitizer/Isopropyl Alcohol was sprayed on the dining table, and all the bowls, forks and chopsticks were properly cleaned and disinfected. It was really excessive.
When their food came, why didn't they clean the soup bowls and saucers containing the food?
