Eric see's the large Asian men.  While he had only heard part of the conversation, it seemed to be a fishy one.  However their was no way of knowing who or what it was about.  Eric casually walks over to the bar and sits down some distance away from the other two gentlemen.  He makes a slight gesture for the Bartender to come over.  He might as well order a drink while he's here, and try and look like a customer.
