That's pretty bad. One of the reasons I'm not working big city. Always lock my truck, too. When I get some money, I'm either gonna re-insure it to the hilt, or go get some customer lock work done - solenoids, alarm that beeps to my phone, etc. Depends upon what is cheaper/better.
I think that crime will get worse.
I'm not sure if I like the "I missed you." tag. Or, if I had one made, it might say something like:
"I'm sorry we missed you, you inconsiderate lowlife. WTF! You still owe me my service call, 'cause I
was here. You'll hear from a collection agency if you don't pay. If you'd like to reschedule, pay my service call, then we'll talk about it."
How would that work out?
