Who knows, maybe it's because of the large number of children who use them because they do not give them proper maintenance. In any case it would be good to consult that with the manager and to fix it. I hope it helps :)
Many parents are careless do not attend to their children.
Because they are under staffed and the drivethru is constantly backed up and employees don't think it's important that children have safe clean place to play. It doesnt matter about how the children are its about not having staff in restraint who think of the fact that THEY are CHILDREN. Kids get dirty
