At almost the end of the movie Dunkirk, when the survivors from Mr.Dawson's boat land and board a train that takes them back to their homeland, Alex makes an assumption that they will be received badly by the British when they do land, as they have been a disappointing bunch.
But instead they all receive a hero's welcome and are given bread on arrival.
They meet an old man who is distributing bread at the survivor's arrival and doesn't look in the eye while doing so.
Alex picks up on this and mentions that to Tommy on the lines of "..the old bloke couldn't even look us in the eye.." to which Tommy doesn't seem to pay much attention.
Was the old man blind or was he just trying to cover his disappointment?
