A person stays in a hotel at night, why does the toilet light have to be on?

First of all, everyone comes to a relatively unfamiliar environment, and the surrounding environment is not as strange as his own home. Many friends have the habit of going to the toilet at night.

Secondly, for those female friends who go out alone, they are usually afraid when they arrive in a strange environment. Turning on the light in the toilet can make them feel a little safe.

The third reason is some urgent emergencies. As soon as the toilet light is on, we can make some judgments quickly, so that we won't be in a hurry when we turn on the light again.
