Not a bass but I was buying something from FB and had a wierdo to contend with. I work in Plymouth and the item was in the city somewhere but he wouldn't tell me where he lived. Lots of bizarre messages later he tells me to message him when I'm nearly there and he'll give me the address, NEARLY WHERE?!
Long story short, I get the address out of him but he will be out, his parents will be home though. I arrive at a very rough area and his mum answers and invites me in, the place is filled with boxes of stuff and she's yapping to me like she's never seen another person, telling me about all the stuff they buy and sell, I can't get away. Her husband arrives home and looks surprised to see someone in his house, she explains I'm buying a VCR, he hands me the box, puts his hand on my shoulder and ushers me firmly out the front door. The VCR didn't work properly but I wasn't about to go back and tell him, they were like the McGuires in Shameless. I'll put that one down to experience
