Unfortunately there is another reason in some areas.  For example a South
Central Kansas Wal-Mart closed its lot to campers after some mindless idiot
dumped his tanks in the lot.  The effect of this carried on to another store
about 10 miles down the turnpike.  I have read of other reports of
overnighters dumping trash and starting campfires in the lot.

We personally enjoy the option of parking in a Wal-Mart, Petro or other
facilities that welcome campers.  This is particularly nice when traveling
cross-country where overnight stays are in late and out early.  It is up to
us to retain the privilege:

- Park out of the way and in overflow lots where available.
- Stay hooked up if at all practical.
- Leave slides in if practical (in other words, look like you are
temporarily parked).
- Go into the store, make purchases and thank the employees for the
opportunity to park.  This latter item is most effective at the service
counter.
- If you overnight at a truck stop, by ALL MEANS buy fuel.
- Leave the area at least as clean as you found it, even if you pick up
after someone else.
