Coin took a break, a young man's travelogue in the US I'm traveling around just swiping with @KASTxyz without worrying about travel costs, withdrawals, or exchanges. It's so convenient.. The cost of living in the US was more expensive than I expected, and the tipping culture was unfamiliar. When they asked for tips, I just gave them, but according to @sungmo_nad, he has never tipped for Uber.
