Ensign Palmer knows that he'll be placed in the line of fire. 3 times has he been left for dead only to rise up again to beam aboard the Enterprise. Being killed is one thing he failed at the academy. Everything else he did just fine. Although he works in engineering he often gets assigned security detail by mistake. There is another Ensign Palmer aboard the vessel but she seems to always get assigned to the lunch room. Pretty unfair if you ask me. Palmer is an amicable lad and is passionately in love with bread. He has often given First Officer Spock a loaf of bread to convince him to re-assign him to more duties in engineering rather than security. It typically fails as Spock seems content to just go down the list and make assignments based on his judgment and no aptitude.
