I never have understood not drinking while J-seating. Sure, in uniform, I would not drink. And these days, I would almost always be in uniform to commute because of the TSA.
But I have jump-seated to Europe several times. Most of those times I got to sit in business or first class and drank everything offered. Why not? ACM? What? Am I going to jump up there and fly for a while? No! (I would never step foot in the cockpit if I had consumed alcohol)
It all a matter of respect. Act respectfully and keep a low profile. If I am offered alcohol on a long haul flight, I will accept the offer.
