I flew 2000 miles to Ohio for the Christmas. Today I when to go try to catch up on a little work at a panera. Because I used my credit card in Ohio my bank deactivated it. I called them about this and the hold music on the phone matched the background music in panera with one and a half seconds of delay. Keep in mind my bank is in CA and the phone number was a 1800 number.
They were probably both playing the classical station on some corporate music feed, still a bit shocking.
