I ran into those guys about a year ago, maybe longer. At the Bank of America ATM near 183 & Oak Knoll. They definitely weren't going to be drinking any coffee since their whole pitch consisted of "hey man, wanna buy some speakers?" I said "excuse me?" because it was such a stupid thing to hear I thought I must've heard them wrong. Then they started with the "we've got extra speakers in our van" bit, I said 'no thanks' and that was it.
