That all sounds worth a complaint to me. For the attitude, but also one of my biggest annoyances is the curtailing of service if they can't be bothered. Hiding away for half a long CE flight and refusing a drink when there's plenty of time strikes me as exactly that. Had it most recently on a flight back from GLA once when the IFL just decided he'd 'close the bar to complete paperwork' once everyone had meals and a solitary drink, and it feels like they're absolutely taking the mick.
