Coleslaw is "aiight" if it's done well.
But in relative terms, yeah, it's the one thing you always throw away.
BBQ spot = ribs, sausage, brisket (and burnt ends), pulled pork, chopped beef sandwiches, hot links, potato salad, mac N cheese, greens/green beans, white bread to soak it all up, pickles and jalapenos, pecan pie, sweet potato pie, chess pie, banana pudding, baked beans/chili beans............................coleslaw.
People that like to dip hot wings or pizza in ranch will eat coleslaw with hot chicken or BBQ. I personally prefer spicy/savory food and don't like putting anything creamy or milky together with it. A lot of folks like that savory and creamy/mayonnaise-ish mix.....so it works for them.
