We burning Hot Dog Buns now?

For the last month over the 3 meijer locations I've visited, all 3 of them have had hot dog buns that are riiight butting up to the edge of being burnt. I've have been checking the bottom of the buns as I've noticed a handful of buns having black scorched marks on them. Idk who is in charge of cooking them or checking, but it certainly seems like someone bumped a temp dial and upped the heat.
