Teaching formal manners as part of pledging/new membership?

[MysticCat]

I can't speak to how much this is taught in GLOs these days, but I am struck by the irony of the brother instructing the pledge on manners in front of other people at a banquet. Not at all polite.

And am I understanding correctly that the brother was instructing the pledge to cut numerous pieces of meat at a time? Or was he instructing him not to do this? If the former, then the brother needs a few lessons himself before offering lessons to a pledge.
