White Spot Stabbing in 1995 or So

I think it was 1995 but it could have been 1996; outside chance 1994. I was working there as a dishwasher. I noticed I hadn’t seen any of the front staff for a bit. It turned out that a woman claimed to have a gun and stole money from the restaurant. A co-worker called her bluff and tackled her (outside I think, but not sure). Well, the good news was that she didn’t have a gun. The bad news was she did have a knife. The co-worker got stabbed. Luckily he only needed a few stitches. I can’t recall if he got back the money or not, but the next day there was a sign up indicating that in such cases, let the money go. They need the staff members alive more than they need the money.
