If the ratchet doesn't have a quick release and the socket is greasy or oily, just bump the ratchet handle on something solid and the socket is off. No muss, no fuss. Inertia does the trick!
At times a non quick release ratchet can be really annoying with oily/greasy hands. Sometimes they don't get easy with time. I've got an F936 that I used daily for several years and now gets occasional use that has never gotten easy to get a socket off of. I have two FR936s and have yet to ever have a socket fall off from the quick release getting bumped. Of course I don't use it for extremely tight access work cause a smaller ratchet than the 936 body is much better for that stuff anyway.
