On shorthaul? You get the exact same packet of 50g Seeberger nut mix just that it is included in the ticket price and there's no charge. Or at least used to get, I`ve successfully avoided flying them post-pandemic and did so only only very rarely pre-pandemic. Others than myself will surely be more qualified to answer that.
And if someone bought all of them at 3,50 a pop before the flight departed as she did to avoid them being distributed, well, you'd get a shrug and "sorry, we've run out" when asking for them...
(haha, I now have this mental picture of the FA telling the passenger "ham r nich, griieche mer ooch so schnell nich widder rein" in a thick saxonian dialect for the true GDR experience....)
