UPDATE and rating increase: After pleading from my kids to go back, I did and was pleasantly surprised! I ordered sauce on the side and no charge or hassle- and, had great service, smiles and two employees asked if I needed anything/how's the food- l'll return.
My initial review in fall 2015: Boo on Wing Stop and their "new registers"- asked for sauce on the side and they now charge $1 for that? What? I can't add my own sauce? Walked out, won't be back and too bad, actually like the food. poor management/owner who decides a $40 wing order isn't work the $1 for sauce on the side...
