Car park crew

The picture is of a man who parks on my car park everyday! Today was the first time i witnessed him checking his doors were locked 10 x then peering in the windows, walking off and then coming back to peer in the windows! Now I have seen a lady also who parks on the car park doing this so I feel it's a tradition and should I start doing it as well to fit in with the car park crew?

Anyway broke up from work now for a nice long weekend happy days!
