Safest/best way to take down drunk people? I work as a bouncer during weekends and sometimes drunk people want to fight me.
 So far I have gotten away with calming them down and/or pushing them out, but a couple occasions have been pretty close to where I would actually need to use force.

Usually it happens outside on concrete so im quite cautious about what I would do. A seoi nage for example could easily kill a person.. 

Maybe something like a osoto gari? Or other leg trips where I can still slow their descent with my grips? Take in mind that these people are usually untrained and drunk so dont really pose a big threat to me.
