Big deal. Mailmen all over the country leave their trucks to go to the bathroom and go and buy lunch. Every day, 6 days a week. What a busy body you are.
With the door(s) to the truck left open? You don't think it's irresponsible being too lazy to simply close and lock the door? Would you go shopping with a carload of valuable stuff in your car without closing and locking the door?
the vehicle was unlocked...presumaby.. and both side windows were wide open and large enough to crawl though
did I not mention this in my first posting in similar terms??
