That is crazy. Especially unarmed.
A couple weeks ago my wife and I withdrew $4K in cash from our bank. As we walked away, I had pepper spray in one hand and my knife in another hand in my pocket, and we watched for suspicious people in the area. We ask the teller to be discrete, but some aren't so we hope no one malicious listens in. We won't pull more than $5K at a time, that's asking for trouble.
My wife won a few thousand dollars on a slot machine in Las Vegas some years ago. She got a hand pay and the casino people insisted on walking us to our car, they gave us no choice in the matter. I thought at first they were kicking us out because they didn’t want us winning on another machine in their casino but most likely they did not want to be responsible for us getting mugged in their parking lot. Winning a large jackpot makes you very visible.
