Bruno Sammartino left the WWF just prior to Wrestlemania IV. Knowing that Bruno was outspoken about things like the drug use and steroids after the fact, what was the straw that broke the camels back, as far as Bruno choosing to leave just before Wrestlemania. Was it a combination of things, or was there an incident that led him to quit on the spot? Did the angle involving the WWF Championship between Hogan-Andre-DiBiase have anything to do with it? We all know that Bruno was a traditional guy, and having the title handled in that manner may have seemed ridiculous to a guy like Bruno.
I'm pretty sure it was the steroid issues that were running rampant at that point for the most part, but I don't know there was one inciting incident that made him leave for good. The Observers at the time don't really have a 'By the way, Bruno told Vince to go fuck himself' report that you can pinpoint. Has he maybe said something in an interview since then?
