To the cynics on here (and those pilots who seriously think you are beyond reproach), I'm not part of your strife with management and this isn't my first post on PP.
Married to a former crew, and if you want to verify my story, go ahead. To the credit of the Captain I don't think he'll do anything - water under the bridge apparently. But, the senior cabin crew will almost certainly file a report. The arrogant, and frankly abusive passenger, upset the crew and passengers definitely spotted that this guy was staff.
