Overnight In Walmart Is Ok

There is some signs saying that is not allowed rv after business closes but only in part of the parking lot. We asked inside Walmart and they said that is ok to overnight. We saw a security car ithe parking lot but they don't said anything. We stayed between 10pm and 10am.
