I completely agree with the point about eating but I opted to focus on drinking behavior and interactions with the hope that people are smart enough to eat, or not show up dressed like a hobo for that matter. One could argue that the entire piece is mute because a person should not feel obligated to drink. In fact there are several celebrities that don't drink at all - Donald Trump, David Beckham, and Jennifer Lopez to name a few, but that's a conversation for another time. I merely wanted to draw attention to the fact that alcohol consumption plays a pivotal role in many business interactions and you rarely hear anyone emphasize how important it is that a person representing a company understands how to properly approach these scenarios.
