Had a dream where this guy and his wife were walking towards a building exit and the guy comes over to me like we know each other to ask a question while I'm heading into some little convenience shop. Maybe it's a hotel or something. The guy is slightly shorter, black hair, brownish complexion, round head, black eyes. He's wearing slacks and a short sleeve blue shirt with thin horizontal strips in a darker navy color. His wife is trailing and wearing a white top with rhinestones, and overdone on the makeup. The kind that looks plastic, long lashes and red lipstick. She's got this naggy voice pleading with him to hurry and and just go outside. I've gathered a few things in the store and at the checkout. The guy walks up go me and asks me if I think he should go out for a smoke. I tell him that I don't think he should. Apparently i know he's been teetering on quitting and I tell him it's his decision no matter what, but that the longer he can go without smoking the better. His wife is getting visibly and audibly upset as she wants to smoke now and saying that he and I are just holding up everything. In the meantime the cashier is doing the order and I tap my payment card. I haven't finished pressing buttons on the screen as I'm talking to these two and out of the corner of my eye i see the cashier working my side of the screen adding a custom tip of $240.00. He presses done and I turn to him annoyed and ask that he undone it. He proceeds to act like he doesn't know what I'm talking about. I demand the receipt and he claims it cant print it out. I see an error message on the display referring to an "ACK UNK 17 @ R PCB". I make note that I will have to dispute the charge with credit card company and write a yelp review. I then head outside with the couple. The wife starts smoking and me and the guy recount the events in the store and then start talking about Bitcoin. There are some things that Bitcoin does fix, and many things it does not. We should spend more time on addressing the things it doesn't fix.
