Do any of you have some customers who think its their business to get up into the cab with you? Ive had customers in the past just get up into the cab and start walking back into the cargo area until I tell them to get down. there are also some who get up into the stairs, I dont like that either and boot their ass back down. What is it that makes them do this? I sometimes leave the passanger side door shut, but leave the window open and if its a small pkg just pop it out the window to them, just like a drive through window. Usually its guys, or old men in the residential areas that are the worst. The thing that I really dont like is when I have the door shut and I leave it shut while trying to find a package, and someone comes out of their house and opens up the passanger door.... keep your hands off grandpa.
