Mixologist behind bar, but not tending it, unavailable for orders

Having this issue as well. Playing the past few days with a teen that will pick up and go to any party/gathering that she gets invited to, so there's been one at the Bluffs, one at each of the nightclubs in Windenburg, and i have also seen it at the San Myshuno festivals that end up opening one of the bars. the Mixologist just stands there forever making bottle towers and no option to order anything from the bar.
