Khan managed this horribly. If he weren't the owner he would be out of the job for how he mangled this situation at every stop. Since he is the owner he should be looking at getting some actual management in place to create better guardrails to prevent future incidents. Maybe this AEW "discipline committee" can be that
Punk in WWE is just a different kettle of fish entirely. They're a much more tightly run organization.
It'd be contractually laid out that he is coming in with 2 strikes and any wrongdoing would lead to immediate termination. Either he would do business or he'd be gone, less risk involved than what AEW endured.
