Best one I have is from when I was an M.A. We did a drive by on this woman who was renting from us and was way behind on payment, saw the car and went back to get a spare key. Went back to get the car later that afternoon, but noticed it about 5 blocks up the street from the renter's house. Turns out, we weren't the only ones looking for the renter or the car. I was getting in the drivers side of the car to head back to the office when a guy asked me who I was and what I was doing with that car, because I wasn't the one he saw park it there. I just said I worked for Enterprise Rent-A-Car and was picking up a car that belonged to us. I started to get back in the car when the woman who was actually renting the car and another guy came out of the building the car was parked in front of. The first guy who asked me what I was doing with the car was apparently the woman's husband, and wasn't very happy about his wife being around this other guy. A Jerry Springer style brawl ensues involving all three of them and a few neighbors who had come out to see what was going on. The car prep and I watched for a minute, decided we should probably roll and then hopped in the cars and headed back to the office. Have definitely gone on some sketchier, more dangerous repos than that, but this one stands out as the funniest.
