Following his exit at the end of episode 12, Frank, an active-duty Marine chef, stated his dislike for female chefs during his plea and claimed he never allowed any to work under him, saying, "The blue team never had any drama until the females came aboard and that's when the ship sunk. And that's exactly why I get fucking female Marines and I send them back wherever the fuck they came from." Following his comments, Marine public affairs representative Bryan Nygaard stated Frank's comments regarding female Marines "are not consistent with the Marine Corps' values of honor, courage and commitment," and he would "notify my chain of command as well as Sergeant Cala's chain of command to ensure that corrective action is being taken." Several days later, Frank was removed from his position with the Commandants' staff and transferred to the Enlisted Aide Program.
The fifteenth-season premiere of Hell's Kitchen premiered to an audience of 3.43 million, 660,000 lower than last season's premiere, and down 10,000 from season 14's finale.
