Just trying to find a water bottle

I’ve been playing this character for hours making it all the way across the map without a water bottle. I ran into these two guys and they dropped me and I lost my sg5k on the ground. I made it away and this other guy pulls up in a car cause he probably heard me going full auto and was attacking the other guys. I pop shot him but I should of hit him twice cause he got back up and is hunting me now lol
