Stealth car dwelling and garbage

I should have also mentioned, when you have a cup or garbage from a food establishment, I then will use the garbage as a ticket to go back to a location to use washroom facilities as the garbage indicates you have made a purchase. When I am parking lot hoping I do the same with certain establishments like Tim Hortons by leaving a Timbit box on my dash as parking lots are patrolled in some areas. I will pack small garbage that is in a ziplock bag into recreation centres where I am showering as I know for certain there will be one available yet I am find access to garbage disposal increasingly difficult.
