My first experience using Google Wallet

I had set up my Google Wallet on Galaxy Nexus. McDonald's is one of the few places in town that accepts contactless payments. I happen to be at McDonald's for lunch when I remembered to try my phone. I go up to the counter and give them my order. They ring me up and happily and eagerly I take out my phone. I open the Google Wallet app and put in my pin, then I tap my phone against the machine. The application force closes on me. I looked like a idiot trying to tap my phone against the payment machine. I am shamed forever. Damn you Google and your half-baked products. I finally gave up and used my credit card. I walked away with my head down humiliated and defeated.
