There are a good four different Carolina styles, what you had was probably eastern NC, vinegar pepper sauce, sweet creamy coleslaw as a counterpoint. Best place I have ever had eastern NC was literally a small concrete block building sort of hidden in behind a residential area, they opened when they felt like it and when they did the lines formed. They had in addition to barbecue, fried cornbread and collard sandwiches. Sounds maybe a little gross but it was awesome with butter and hot sauce.
Yeah buddy!
