Answer 1

I have been a cleaner in an airport, office, and pub. I’m currently a receptionist/cleaner for a charity.

I can tell you that public toilets are the same. It’s just that the cistern (tank) is hidden behind the wall. There is a walkway behind there, most times. I’m at work in a couple of hours. I’ll post a video of our setup, later, to show you what I mean.
