Can male guests ejaculate in hotels' dispenser bottles? [closed]

You do realise that a single-use bottle of conditioner passes through quite a few people before it ends up in the hotel room, you're going to use, and any of those people might have replaced the contents with anything? So this doesn't really pose any new problems.

At the hotels I've been at in the last many years that have done this (Marriott is far from the front here), the dispensers have been closed, so it would take some effort to open it. I must admit that I never bothered to look so closely at it as to figure out how to open it. Furthermore they're placed such that I think you would have to be in a rather uncomfortable position to jerk into it.
