Is it okay to drop my tip out beds at rest stops or Walmart?

To some who seem to resent folks overnighting in Walmart lots for whatever reason I will say this. I think most people who stop overnight at Walmart are NOT there to avoid paying camping fees. They are there for convenience to get a little rest. If there was a campground next door to Walmart I a sure many would choose that option.

Also, I would much rather someone stay at a Walmart parking lot than come driving into a campground at 10PM and raising a ruckus setting up their rig for just an overnight stay.
