"Listen, ma'am, I know it's a hot day out and you're probably looking to cool off a bit. But this is private property, and you're not in any old pond, I built this fountain pool and I try to take good care of it. I'm worried your hooves will scratch up the liner at the bottom. You're already making the water a little cloudy...I'm not levying any accusations that you're filthy or anything, but suffice to say this isn't water for washing up in or dripping your goop into, I filter it to keep it nice and clean. Please step out carefully and then you can go ahead and present whatever you were presenting."
