Quite rude to say nonetheless
The rule I make is when someone else is paying for the meal I order a meal that is around the price of what the person is ordering. I also take directive if the person is ordering a drink I know I can order one,but if the person is just having water I stick with water.Now if I'm on my own moolah then it's a whole different story.
Actually when going for an interview the boss to be looks at your maners or even if it's just a friend going for a casual pizza. No matter what manners are so important. Do you want to be eating the $30 d ollar Fillet Mignon when the person treating you is eating a $12 dollar salad? I don't think so.
Oh and another habit that I can't help but notice is if something is wrong with the meal the person will complain in a unprofessional manner. Come on people you need to read books on Ettiquite if you think you can pull of bad habits.
The eaisest way is ask your self if Ann Landers were here would she like what she saw? This is what I ask myself to keep me "in tune" with the whole dining experience.
Just my 2 cents.
