Hehe, well where I currently work part time has no security as it's a fairly small shop. I found some bloke in the back storeroom, he made a break for it and I followed, out the back emergency exit, round the store, to a main junction where he got in a car and drove off (I got the reg). I walked back into the store where my coworkers where looking for me (I had shouted to one of them to bell for everyone else before I dashed off but they lost where I had gone after heading into the stock room). I was very very winded, as I am nowhere near fit enough to run that fast for that long on a foggy night. A couple of customers came over to talk to us and it turns out that the car the bloke had got in had been pulling up to our loading bay doors when me and the guy ran out the back. So obviously the plan was for him to open the doors and them to load up with anything they could get their hands on.
It really was stupid for me to chase him though, it was night, I was on my own, I am seriously the least threatening thing ever and he had two mates in a car so things could have gone very differently...
