Google Wallet- Has anyone been able to get it to work?

So, I just got my Galaxy Nexus off contract and I'm in love with it.(I'm moving from an iPhone 4S) I set up Google Wallet last night and I went into a McDonalds and made my order, put my phone against the card reader and the app opened. I entered my pin and it told me to try restarting the phone. I did that (while looking like an utter idiot) and tried again. Still didn't work.

I did this later that night at CVS trying to buy a Pepsi. (Again getting the weirdest looks from the casher)

Has anyone gotten this thing to work? Is it that it only works properly on machines that have the Google Wallet label on them?
