Ordered 2 subs & wings. Both sandwiches were wrong! Their excuse was they had 5 subs coming out at the same time & they went to the wrong people. If you can't keep orders straight then maybe you shouldn't be working in this business!!!! They are redelivering but I didn't need the attitude when it wasn't my fault you messed up our order!!!!!
