Mace and a tazer gun... Personally I would go for a cattle shock prod so that I could give him a good jolt in the nuts from a distance, but a tazer gun would work too!
Just an opinion, but you simply have to stop thinking of yourself as disposable. You are not a napkin to be thrown away after a meal. If they require you to work late and be the last one, they need to ensure you a safe passage to your vehicle. You are worth more than that!!! I know it is hard, but value yourself and your own safety enough to ask for help. It sucks that he has destroyed your ability to see your value. Don't give him that power anymore! Hang in there!
