To be contrarian, I usually deal with rinsing and cleaning when I get home. I rinse the tank through the toilet with a garden hose then drain into a bucket and properly dispose of the rinse water.

Not necessarily a better solution, just one that eliminates having to carry another waste hose and having to futz around at a scuzzy crowded dump station. It all depends on what you consider the bigger hassle.

I should note, however, that we've never used our black tank for, um, solids. If we did I might be a bit more particular about rinsing out at the dump station!

It is certainly interesting to watch people at the "dump stations". You see everything from using nothing but maybe a pair of gloves (me) to a full hazmat suit. I am typically dumped and gone while others are still suiting up. 

Bottom line, do what makes you comfortable. Even if you have a catastrophe (watched that a few weeks ago when the black tank was opened without a hose connected), it washes off with a bit of soap and water.

As you describe it, I don't think that's something I would worry about as long as you still get the same water pressure when you ask for it. I think there is a small filter on the pump itself, maybe check if it needs cleaning?
