Whatever parenting book this guy read needs to be recalled... assuming he knows how to read.

Police say Donald Christian Rombough, 26, left his six-year-old son in his truck in the parking lot of Stevie Tomatoes Sports Bar in Fort Myers, Florida. Apparently, Rombough wanted to watch an Ultimate Fighting Championship match in the bar.

Police say the Rombough also had marijuana and paraphernalia.

Two women called security when they heard the truck's car alarm go off and saw the child inside, crying.

The boy's father came out, and told security he had to go back inside because he had food waiting, according to Naples News.

Police say the boy was slightly dehydrated. He also suffered whatever damage comes from having a complete idiot for a father.
