It was there the eight-year-old asked for his favourite drink – a root beer.
But when the trainee server brought the bottle out, it tasted nothing like Tyler remembered.
“What do you call that? Throw up root beer? Cause that's what it tastes like," Tyler was quoted as saying by KTNV.
Tyler’s mum and dad both then tried it, and soon realised it had alcohol in it.
His mother was particularly upset that he drank the alcohol because he has a heart defect and is on ADHD medication.
Moreover, the bottles for the non-alcoholic and alcoholic root beers didn't even look alike.
She added that discovering the root beer was alcohol gave her son a mighty fright.
The trainee server and manager both apologised and the bottle was removed.
The family said after the incident they were told by the company that a new bartender was training that day, and that they mixed up the bottles because the two root beers are located in the same space.
T.G.I. Friday’s said it was an honest mistake and that they immediately addressed the situation.
“We are currently retraining staff on all operational procedures and responsible alcohol service standards to prevent a recurrence,” the company said.
“The safety of our guests and team members is the utmost importance and our top priority.”
Tyler Schwab and his family recently went out to eat at a T.G.I. Friday's inside The Orleans hotel and casino in Las Vegas.
