The following is an exam review question, I have already worked through it but could use a second opinion. Thank you.

Jack is a customer of Mexican Rose restaurant.Jack orders a chicken enchilada and sustained throat injuries when he swallows a chicken bone.A customer at the adjacent table, Sammy Samaritan attempts unsuccessfully to do the Heimlich maneuver to dislodge the bone.Jack suffers broken ribs for the Heimlich hold.Jack sues the restaurant and Sammy for his injuries.

What, if any, are Jack's possible theories to recover? Should he prevail? Why or why not?
