Every chance you get, either concealed carry or dumpster dive for a cup, barge into a restaurant, cup hidden in bag/jacket or not, then just help yourself to a refill of your favorite drink on tap. I do this as much a possible. Everywhere I drive, I'm always eyeballing restaurants to see if I can access the drink machines. If the machines are far enough from employee visibility, I tuck away my and move in for that cold refreshing beverage. I prefer big cups, something about soo much cold refreshing beverage just lifts me off. I have several favorite spots. I'm always politely nodding in public, holding doors for grandmas, etc. and nobody knows that I didn't pay for my drink that I'm slurping under my mask with a shit eating grin. I like to spend a long time at the fountain, trying flavors, even though I always settle on the one. I don't mind that paying customers have to wait a little bit on me. I don't take that long anyways. But I could go a really long time, if circumstances allow.
