Why are the glass in hotel rooms and bathrooms transparent?

At present, almost all bathrooms in hotels are transparent. There should be three reasons: first, most people like to turn off the lights to sleep, so when they rest at night, because the bathroom is transparent, they should turn off the lights, which can save electricity. Second, if you live alone, you can see if anyone has come in to steal when you go to the toilet. Third, some people are not used to being seen going to the toilet, so they need to open an extra room to increase the hotel's income.

The above is personal opinion, purely manual.
