Something that is completely unnecessary for a modern man is the lack of protocol or what is right to do. A man’s duty is to know how to behave in all situations. Last weekend, I was at a family wedding when I noticed some of the men around the room had no idea how to behave in a social setting. I also noticed some of the men had no table manners at all and some of the women, too.
A man should at least know the basic table setting, if nothing else, before he heads out the door to a function. It only takes a moment to take to memory where the glass goes, plate is, etc.. You will not only be more relaxed but also impress your guest/date/boss. Now days, employees are judged by their manners or lack of when dining with employers so take note.
