Are you saying you fly a lot of economy class flights between the US and Europe? Not a month goes by where I don't hear German- or Dutch-accented FAs asking someone in economy class to unrecline the seat during at least meal service. There are months that go by where I don't hear US airlines ask this on TATL flights. And I fly the US carriers way more than I do the European carriers when it comes to my TATL trips.

Recline your seat in economy class TATL on AB, LH and LX several times a quarter and try to keep it like that during meal service. Then see for how long your "never" remains "never".
