Are you aware that deplaning by rows is supposed to be for pax safety due to deadly Covid than just to ensure a more pleasant process?
Its a mockery to deplane by rows onto buses because I am quite sure for an Airbus LH don't send 6 buses to ensure adequate social distancing. Only a moron could imagine that deplaning row-by-row to a crowded bus makes any sense.
Plus there are no HEPA filters on the bus and standing up is way more dangerous than sitting down.
