There was a period of time when I resold electronics on ebay.
One afternoon after work I went to go meet a guy to buy 2 phones from him. A few minutes after parking I saw him walking across the street towards me. I saw something sticking out of his waste that was tannish green. As he got closer I was able to see it was a G18 mag.
We shook hands, I checked out the phones, then handed him the cash. Right after handing him the cash I said "I like your piece" and flashed my CCW. He smiled and we dapped up.
One of my more real experiences I've had. Small but significant.
