Dump Station Newbie etiquette

So I have all the gear for the black/grey tank purge and have done it 4 times in the 1st year of owning the Pod and feel confident in what I need to do...but those events were twice in the private campground camp site and twice using my backyard septic tank cleanout.   I've never used a public dump station so my question is about the normal expected time for the process.  I timed it last night at my house and figure about 20 minutes total.   Is this a good time?  Translation, if a fellow RVer is waiting behind me at the dump station, how long will it be before he starts getting impatient?  Should I pull out the NASCAR pit crew playbook and study it?  Don't want to rush the process but don't want to piss anyone off either.

I had already thought about dumping then having the wife pull forward out of the area to get re-organized including adding chemical and water.  And I was using the black tank flush but didn't totally refill the tank....more like a rinse till I saw clear liquid.  Thanks for the response.

If there is a line.. I hook up the sewer hose, do the dump.. go on. The tank doesn't need to be rinsed vigorously every dump. I do it a couple times a year, at home. (FHU's here)

It's more important in my experience, to make sure you have PLENTY of liquids in the black tank to help solids move along. I have found that a tervis tumbler is just the right size to put behind the flush handle to "top off" the black tank before rolling to the dump station. You can also use one of these.. but that's one of them there unitaskers..

The point is.. you will never ever ever ever get the tank "clean".. it's had poop in it. Empty and go.Rinse any extra when convenient. We have never had a clog, ever, on the "exit" side. Someone in this camperhold has stopped up the down pipe. I ain't naming no names, but.. it wasn't me or the dog.

I hope you and Dixie are never behind me, waiting on me....
