If Tony Stewart is stressing out over his lack of success on the NASCAR circuit, he's doing a fantastic job of hiding it.

Fox Sports' Shake and Bake blog reported that Stewart, currently 26th in the NASCAR Sprint Cup Series points standings and winless on the circuit since June of 2013, drove up to an Arby's fast-foot restaurant drive-thru at an undisclosed location and ordered some food.

Another winless season to make Tony Stewart consider retirement?

Shake and Bake offered video of the event (from Tony Stewart Nation on Periscope), in which Stewart disguises his voice and then engages in an amusing conversation with the Arby's drive-thru employee who tells him he looks like Tony Stewart when Stewart reaches the window.

Apparently driving in a Stewart-Haas Racing-identified vehicle, Stewart announces to his unidentified passenger, that when he thinks they are found out, the Arby's employees are going to spit in the roast beef sandwiches he orders.

Carl Edwards calls Tony Stewart NASCAR's worst athlete

Stewart also prefers Arby's Sauce to Horsey Sauce.

"How are you hooked to Tony Stewart Racing," the drive-thru employee asks.

Stewart: "I just work for him."

Employee: "You look a lot like him."

Stewart: "I know, we get that a lot."

Employee: "I didn't think you were him, but you look like him."

Stewart: "Nah, nah. I wish."

Employee: "You wouldn't be worried about getting something to eat (if you were Stewart); you'd have somebody else getting it for ya."

As the drive-thru employee closes the window, Stewart mutters, "Jackass." in response to the employee's assumption.

In addition to being extremely polite at the drive-thru speaker, Stewart also proves that fellow NASCAR driver Carl Edwards may be correct in calling Stewart the worst athlete in NASCAR, thanks to Stewart's lunch of two regular Arby's roast beef sandwiches, an order of curly fries and a medium Coke.

Stewart still is trying to get a breakthrough win after the tragedies of 2013 (a badly broken leg in a crash) and 2014 (involvement in the death of fellow driver Kevin Ward Jr.), both events taking place in dirt-track races.

Stewart has yet to race in another dirt-track event. His videos, however, show him to be a regular guy and could be cathartic in his attempt at a racing resurgence.
