BBer - "Dropping the weights bothers me - stop that shit right now."
OL - "This gym is specifically setup for performing the olympic lifts as most serious gyms are and that involves a controlled drop to the floor. You can confer with the management if you'd like but the best I can do for you if it's truly disruptive is to offer to alternate the timing of our sets if you are performing a serious exercise and you feel you are in danger. These exercises are important to me and very effective for building a powerful back and massive traps, you should try them sometime - I guarantee you won't be disappointed. I'd be willing to help if you are interested."
BBer - "Cool. Thanks for that. I might take you up on it sometime. My name is.....what's yours?"

Very easy stuff. Roid rage is real but it can be drastically mitigated by a calm mind and friendly demeanor. Treat others how you would like to be treated and if you find yourself receiving the raw end from someone else be firm but show them kindness and understanding. It usually serves to diffuse any situation. If that fails, offer to go with him to speak to the floor manager. Involving a neutral third party with authority tends to help also as does isolating someone everyone watching as some people seem to get off on just making a public spectacle.
