Instead of quitting immediately, I’d at least type in the quick chat asking them not to take any weapon they see from lockers. A lot of the time these people dont understand the unwritten rules of Horde, so explaining it to them could go a long way. If the problem persists, then yeah, I usually grab their weapons and chuck them while also blocking their path before quitting lol. Petty AF
… however most of these issues can be fixed by sticking to customs and playing in higher difficulties. My Horde experience skyrocketed after deciding to only play incon - master Customs.
