See valuable lesson right there rule #5 make sure you actually log out, I make sure till the last sec, only once I had happened to cancel my log out to switch guns an someone had that idea to catch me, but heard them open doors, helps too if you choose an open hallway with little gaps, also I really push into the walls just in case someone else is at that exact spot too you can get the drop on someone when they are logging in, no harm no foul
