Five days away from the College Football Playoff semifinal matchup in the PlayStation Fiesta Bowl between Ohio State and Clemson, an on-campus bakery and cafe chain threw an early jab at the Tigers for the Buckeyes.

The Panera Bread locate at 300 West Lane Avenue in Columbus, Ohio, had a message for No. 3 Clemson (13-0) and head coach Dabo Swinney as the Tigers take on No. 2 Ohio State (13-0) Saturday at 8 p.m. ET on ESPN.

Ahead of kickoff from State Farm Stadium in Glendale, Arizona, the sign outside the store said, in capital letters, "Clemson is made we don't serve cupcakes."

The troll stems from Clemson's soft schedule, which included non-conference opponents such as Texas A&M, Charlotte, FCS Wofford and South Carolina before the Tigers waltzed through the ACC — regarded as the worst Power Five conference in college football for 2019.

Meanwhile, the Buckeyes beat conference champions in the C-USA's Florida Atlantic and the MAC's Miami of Ohio, in addition to AAC runner-up Cincinnati. Ohio State then went through the gauntlet of the Big Ten to close out the season, beating three straight top-15 teams in the CFB Playoff rankings in Penn State, Michigan and Wisconsin.

Swinney has been vocal about Clemson's perceived lack of respect since the Tigers' Sept. 28 close call at North Carolina, when they escaped with their 21-20 win over the Tar Heels.

"The 'ROY Bus' is fueled up, for sure," Swinney said Dec. 12. "It's been easy this year. I really haven't had to do a whole lot. Pretty well stated on that, I think, on the record on all that stuff. I think, as a coach, you take free fuel any time you can get it."
