perverse housework - golden shower waste?

Unfortunately, there are sometimes situations where you don't have water when you need it. But surely you can wash up with golden showers? Is that perverse? Because people, possibly even strangers, want to use the crockery and I just piss on it. Somehow I have a guilty conscience but at the same time I think it's cool. But the other question is whether you think my champagne is wasted. Can you do something like that or would you rather have every drop in your mouth?
