If a server is stabbed with a knife causing serious bodily injury due to an upset customer, what offense has occurred?

The scenario describes a situation where a server is stabbed with a knife, leading to serious bodily injury. This constitutes aggravated assault. Aggravated assault is characterized by an attack that results in serious bodily injury or involves the use of a deadly weapon. In this case, the knife is a deadly weapon, and the injury sustained is categorized as serious, meeting the legal definitions for aggravated assault.

Understanding this context is crucial because it distinguishes aggravated assault from other forms of assault. For instance, simple battery would involve less severe physical harm without the use of a deadly weapon, while regular assault may not result in actual injury or may be defined simply as an attempt to cause harm. Therefore, given the details of the incident, aggravated assault is the correct classification of the offense.
