Can I have password for my hotel room's shower?

A conversation you never get at a hotel when you check in:
"how many people will be having showers?"
"oh, three of us"
"OK, here are three vouchers for hot water. Keep them handy as you'll need to retype them at random points in the day"
"thank you. Is the login screen in a random EU language and in a font that looks really tiny when I try to enter it, with a random set of characters that are near impossible to type reliably on an on-screen keyboard especially as the UI immediately converts them to * symbols out of a misguided fear that someone will be looking over my shoulder trying to steal some shower-time?"
"Why, yes -how very perceptive of you. Oh, one more thing -hot water quotas"
"hot water quotas?"
"yes, every voucher is good for 100 Litres of water/day. If you go over that rate then you will be billed at 20 c/Litre."
That's a lot!
"Yes, we recommend you only have quick showers. But don't worry, the flow rate of the shower is very low on this hot water scheme, so you can still have three minutes worth of showering without having to worry"
"'this' hot water scheme?"
"yes -you can buy a premium-hot-water-upgrade that not only gives you 500L/day, it doubles the flow rate of the shower.
"oh, I think I will just go to the cafe round the corner -they have free hot water without any need for a login"
"if that is what you want. Is there anything else?"
"Yes, where is my room?"
"It's on the 17 floor -the stairs are over there. With your luggage you could get everything up in two goes -it will only take about fifteen minutes"
"17 floors! Fifteen Minutes! Don't you have a lift?"
"Ah -do you mean our premium automated floor-transport service?  Why yes, we do have one. It won't even add much to your bill. Would you like to buy a login? First -how many people will plan on using the lift every day -and how many times?
