Is it uncivilized to gargle in the sink in the canteen?

It depends on the specific way of gargling. If you gargle with your hands or a cup lunch box, it's nothing, but if you face the faucet directly, it's a bit indecent.

In life, there are many such situations, and many people think it is not a big problem. It is normal to eat and wash dishes in the canteen, and it is normal to wash dishes and gargle. It's much better to wash away the water than to throw it in the trash can.

The sink is specially used for washing dishes, and dishes and chopsticks are all tools for eating. If you spit mouthwash in the sink, you will feel dirty. Pay attention to keep the canteen clean, and no one is allowed to gargle in the sink.

From a sanitary point of view, it is recommended not to spit in the sink. The place to wash dishes had better be dedicated and clean. Mouthwash will contain oral bacteria when spit out. If it is unsanitary to touch tableware, it is better to spit mouthwash elsewhere.
