Last month (November, 2011), 11 people at our office in downtown Mountain View were hit with credit card fraud. Most of us eat at the same group of restaurants on and around Castro Street in Mountain View. I was out of town, and was thus spared being a victim. However, I returned in late November and resumed using my credit card for lunch in downtown Mountain View. A couple weeks later, my American Express was shut down for fraudulent activity. It had been used at two Home Depot locations: one in Pennsylvania, and one in New York. One charge was for over $700, and the other for $450. That makes 12 credit card fraud victims at our company—a significant percentage. The logical conclusion is that a someone who works at a restaurant in downtown Mountain View is stealing credit cards. If you're headed to Castro Street to eat, it may be prudent to either 1) go somewhere else, or 2) pay in cash.
