Etiqutte- table coaching

[SofaCoach]

Going to Vegas for first B&M game after alot of online play. I posted the other day requesting some general etiquette questions and got many good responses, thank you. But I have one other specific question:

I have played alot online and am confident in my overall game. However, I am going with one friend who has played very little hold em. What is the etiqutte regarding giving strategic advice at the tables? I know not to say anything during a hand, but after the hand is over is it OK to give tips like "you should have raised that pre-flop since you were the first in" or "just throw away that K9 offsuit next time".

TIA guys (and gals?)

I think it depends on the amount of advice and coaching you are giving. If after every hand you give advice, most everyone at the table will start to get irritated. If instead you selectively give advice, and only when asked (you should work out a way for you to signal your friend), then most people will be OK with it as long as you don't point out other people's play (that would be giving the table too much information).
