LOL. Yeah I'm in the carry some cash with me boat as well. I once was travelling and had no cash on me. Got to a place that their card readers were down. I had money but no way to get to it. So I had to find an ATM which isn't always easy when you're not familiar with the area. I decided then that I'd always have cash on me as there is nowhere that doesn't take it and it's never down due to communication issues with a server.
