Sometimes you really need to do it yourself if you prefer a job to be done right.
Personally, I don't think that's "doing it right". Actually, I think it's a really bad idea. First off, if you drive the car before changing the oil, the "dirtiest oil" isn't going to be at the bottom. More importantly though, draining the oil pump completely dry isn't really a great idea, as you're going to have pretty low oil pressure on the first start. The only time I've seen the "low oil pressure" message on the dash is when letting it drain too long, and it also sounds horrible on the first start. A little bit of left over oil isn't doing any damage.
To the OP, just go back to Jiffy Lube, and watch them, making sure they use the correct oil. "Jiffy Lube" isn't a dirty word. Yeah, in the future you should find an indy to do it, but I'd have them make it right since you already paid for it. I've done one OC on my current car at a dealer and they screwed it up, so dealers and independents aren't foolproof either. It's not like they have their most experienced personnel doing oil changes...
Lastly, 20 miles on 5W20 isn't going to do any damage. Viscosity is related to temperature, and you're still getting up to temperature for the first 20 minutes or so.
