We walk right up to them with that cheerful, friendly customer service mentality and ask; "May I help you? We'd be happy to show you around!" Most times it's a Realtor rep taking photos or something to deal with a refinance and they want pictures of our place. Whew!
You only live once, but if you do it right, once is enough!
I am not an attorney, just an experienced manager who is willing to share what I have learned. Your thoughts, practices or opinions may vary and neither of us may be right.
Yes, I have a couple of time's. Being in the location/city that I'm in and in the instances that I've encountered this and by the looks of the people in question I will not endanger myself by physically going up to someone's vehicle, however; I did (do) write down their license plate numbers with vehicle information/occupant descriptions and vehicle description and day/time I saw them. Nothing (thankfully) has ever come of those couple of instances.
I start by walking out and offering assistance - if they give me no real answers I then I have no problem walking out with my camera taking their picture - If they are brave enough to question me I tell them that photographic evidence is better in court then me just writing down their license number - it also helps the Police find the correct vehicle!
Most of the time once I confront them they leave.
All arguments can be resolved ... with high explosives and Humor!!!
I had a car pull in the parking spot and I saw a girl roll down her window and take a picture of the side of the house. I wrote down the license plate number. The next day a storage unit was broken into and the fence cut and a motorcycle stolen from the unit.
I gave the footage and the license to the police the next day. It turned out the tenant had stolen a motorcycle and the person he stole it from stole it back. Then the tenant saw this person and beat him up and went to jail. We later auctioned off his two units.
On Memorial day about 4 in the morning I heard a car door and looked out to see a car parked in the parking spot. I waited about 20 min. and then called police. The police officer came and I watched from inside as he got their id's and then drove off. The people stayed in their car. I finally went out with a flash light and told them they had to leave. They said their transmission was going out and the officer had told them to have it towed. Apparently they chose my two small parking spots to park the car for the night and were sleeping in it. They had the car towed but kept me up for two hours with their arguing and slamming doors.
If someone comes in and starts asking about the security cameras and takes a great interest to how many cameras I have then I make certain to remember the details about them. It usually means trouble.
