I always thought it would be profitable to put "Anger Stations" that provide these services right by gas stations on really congested freeways. People could pull off break as much thrift store garbage as they like for a fee. Different anger fantasy theme rooms like a cheesy motel but way better with different settings. Special request settings for the discerning and wealthy customers.

There are problems with the business model. There would be a lot of liability; waivers would have to be signed, appropriate safety equipment provided. I'd definitely want to steer clear of any hate crime scenarios. Non representational objects would probably the wisest route. Then there would be the other problem of guaranteeing the safety of employees when working with a rage filled populace. So I guess what I'm saying is you're not the only one that's given this quite a bit of thought.
