I stayed for an entire month without problems. They do come through eventuakly and kick everyone out. It was almost 7am and about time to get up and ready to work anyhow. The guy that does it is nice as long as you are. Don't make a mess or be obvious. I am in a van and blended great. Others made it like a KOA and got their attention. WinCo employees are friendly. One told me what to expect etc when the time came to be told to leave. There is a small casino in the store and ice for $1.98 if you need it. Also restrooms and it is 24 hours. I felt perfectly safe.
