Ok....so the wife and I stopped to get Taco Bell (not our usual to-go go-to...but we won free tacos at the hockey game last night). While we were waiting for our order, a homeless man came in to the store. He wandered about for a minute or two and then suddenly swung a high leg kick in the direction of another customer standing about 15 feet away from me (he missed). The customer said, "whoa...what was that?". The homeless guy walked to the far end of the seating area and the customer returned to looking at his phone. I got a strange feeling and kept my eye on the homeless guy. Suddenly he picked up a chair and started to go straight for the customer (who had his back turned at this point) chair raised above his head. I immediately stepped forward and said, "no, no, no, Hey! don't do that", which, strangely, stopped the homeless guy in his tracks. He put the chair down and tried to act like nothing was happening. I told him to "get out!" And he left. Now those of you that have met me know that I'm not in any way intimidating and I didn't think of myself as the kind of person that would get involved...but if I hadn't said anything (or even been there) I'm certain that the customer would have taken a chair to the back of the head (and in front of his two sons). My wife called the police (who didn't show up) and I watched to see that he left the immediate area. The customer thanked me for having his back. Not the kind of evening I was expecting to have.
