War Z stories

I started this because I ad a aggravating experience today playing. Ran solo into nearby town with no upplies or weapons, figureI'd give it a shot and see if its do-able. Gotinto town found a couple supplies and got sideswiped by zombies. I then found a truck to jump onto but with no weapons, I threw out a help message. I only did this cause I heard zombie grunting and gunshots nearby. Well eventually two players found me in the truck, dispatched the zombies and I thanked them. I then proceeded to a building to find a decnt amount of supplies and TWO mossberg shotguns. The players were still in the area so I asked them to meet outside the building as I found something to give them in return for helping me. I dropped the first mossberg at their feet and as soon as I went to drop the second they killed me. Seriously WTF and I was being nice. I could have just turned around and blew their heads of and took their loot. Moral of the story. someone is kind to you keep an eye on them regardless.
