Don't hand your son a beer for five seconds at AT&T Stadium this season Cowboys fans.

This actually took place during the last Cowboys preseason game in Arizona. Arizona Cardinals season-ticket holder John Coulter wanted to take a picture while at Saturday’s preseason game. The only problem? He had a beer in his hand. So he asked his fifteen year old son to hold the beer while he pulled his phone out of his pocket to snap a picture.

A few minutes later Coulter and his son were escorted out of the stadium by two undercover officers with the Arizona Department of Liquor, who said what Coulter did was illegal. “I thought it was a candid camera joke, I really did,” Coulter told USA TODAY Sports.“We just watched the opening kickoff and I wanted to take a quick picture. I literally handed my son my cup and said hold my cup, I reached into my pocket, grabbed my cell phone, put it on camera mode and took a picture.”

That’s when the undercover officers approached Coulter and said he could be arrested. “I normally would support the police if I heard a story like this,: he told USA TODAY Sports. “However in this case I was standing right there and I witnessed abuse and overzealous pursuing of the situation. It was totally uncalled for."

An officer told USA TODAY Sports that Coulter was lucky he wasn’t arrested for having his son hold his beer. “Providing alcohol to an underage person or an underage person in possession of alcohol is a Class 1 misdemeanor.” said Sgt. Wesley Kuhl of the Arizona Department of Liquor License and Control. “The consequences could be up to, and this is a maximum, of two years in jail, $2,500 fine and three years probation.”
