Oh dear!I would never salute any flag or recite any pledges (vows) or stand up just because some tune was playing. I come from a (Quaker) tradition where these things are thought of as worldly vanities.
I had hoped that I wouldn't need to point out that, at least in my understanding, the worst of bad manners is in pointing out the "bad manners" of others.
Now I've done it. Sorry.
