Office restrooms have a completely different use case - they're not trying to turn over occupancy as quickly and cheaply as possible. And none of the office restrooms I've been in have ever used bar soap. And I have input into my office building's selection - I get to complain to the office manager who can then complain to the building management. The result is, typically, some hypoallergenic liquid or foam that doesn't over-dry most people's skin, so they have little reason to bring their own.

In small offices if someone has a preference on soap they can usually get the office to stock theirs or at least bring it in.

And based on what I’ve seen, the numbers are about right.

Add in those who basically never use the hotel room but to sleep and you can get the one in seven.

I've considered it. Most office soap smells so bad. With the exception of Microsoft's soap. It's been close to ten years since I worked there, but I can still remember how good their hand soap smelled.

I can't remember the last time I used an office restroom.

Your prostate (if you are a male) is apparently still the correct size.

I’m working on location this week, I drank about 2.5 litres of water today. If you aren’t peeing during the day you aren’t drinking enough.
