Revenge is dish served on death row

It took 23 years for the state to execute the prisoner.
Lawyers, judges, politicians, and an endless parade of activists posing as experts did their best to keep delaying the execution, but eventually justice was served.
Why was he executed?
Twenty-three years ago, the prisoner killed a cafeteria worker.
Apparently, he didn’t like what was being served then, either.
As they put the needle in the prisoner’s arm, he vomited.
It’s a common thing to happen.
But I’d like to think someone in the cafeteria gave him food poisoning for his last meal, as a final kick in the teeth.
