On Wednesday he entered Tang's Pacific Bistro on North Beach Street in Fort Worth, dressed in polo shirt and soirts.
But he stepped behind the counter and started having words with the wait staff and customers.
And then he became the opposite of casual, pulling out a semi-auto handgun, waving it at everybody and then fleeing with cash from the till.
One customer grabbed her phone and recorded his getaway.
You can see all this on surveillance video provided by Fort Worth Police. They want your help catching him.
