While wearing a hat or not is considered bad manners and disrepectful is, to a certain extent,a matter of culture and circumstance. Unless the hat is a problem in terms of e.g. obstructing a view, I tend to take a live and let live attitude, as I have a choice of whether or not to be affected by it. I do however get upset with those who insist on smoking in restaraunts. Those who do so I regard as totally self centred and lacking in any consideration or manners. Just because they themselves may not be eating at that precise moment - no one else matters to them. They have a choice - they can get up from the table and move to where people are not eating - but this apparently does not occur to some people. I am not saying that those who chose or are addicted to smoking should be forced to give up, merely that they should have some consideration for the effects of their choice on others.
