Current position is 17/hr + Tips & they're actively advertising a 2 dollar higher pay rate. ​ And no they haven't offered the current employees a pay raise and isn't going to give them one. https://preview.redd.it/63yam8m51xza1.jpg?width=1875&format=pjpg&auto=webp&v=enabled&s=44d927ea0bb274d678e9b824a6d361a771feece2
