I strongly dislike letting anyone into my place. I had a break in many years ago, it really does change you.
In those days I had a 2 bedroom apartment and I had comics in frames all along the hallways. I had a technician in to setup my internet, and a couple of days later several of my comics went missing. I can't prove it was that tech, but I am sure it was him.
My favorite transactions are out of my car. One time I had a frequent buyer contact me looking for a few books he knew I had ( he sold them to me! ), and knowing what type of books he likes I seeded my trunk with boxes of books. We meet up in a McDonald's parking lot, and I tell him the books are in the trunk and I open it up and he sees 6-7 longs of books. He asks "what is all this?" And I say I hadn't unloaded since the last show ( a few weeks previous ).
Sure enough he looked through the boxes and bought more than he planned to
