I have a habit of going on mini-crusades. Sometimes I share them with people, trying to get others to fight the good fight. These causes can range from "I'm no longer buying Nike shoes" to "I'm not reading about Scott Walker anymore." 

Currently I'm in the midst of a "Back to Cash" movement (of one). Last Sunday I was on my home from Wrigleyville. Luckily enough I dodged a Cubs game, but unluckily I ran into Sausage Fest (the street festival). Getting back to Logan Square from Wrigleyville on the CTA is a bitch. Transfers are a must, and there's definitely going to be a bus ride involved, likely with a sizable wait. I was looking at an hour, easily. I ran in to a convenient store to grab a drink. 

"Sorry. We have a minimum charge," said the man attached to the finger pointing to the sign in front of my face posted on the bulletproof glass between myself and the man behind the register. 

"Nevermind," I say, put my drink back and leave. I catch the Red Line to the Brown Line and then the bus at Diversey, where I was again told "I'm sorry, we have a minimum charge."

Something about this "minimum charge" concept makes me feel like I'm paying a fee to pay. Like we're being taxed for giving people money. It's not always the fault of the business owner. I once met a bar owner who told me that he pays nearly three to four thousand a month in charge fees. So my latest mini-rebellion is a move back to cash payments. At least for anything under five bucks.
