Several years ago, took the short DFW-AUS flight (the old airport). Two apparently novice FAs served drinks in a very leisurely fashion. On approach to AUS, they were told by a superior to cease service and stow. They continued for several more minutes, unperturbed, and I began to wonder what was going to happen. Suddenly, the superior appeared again, and said "Stop NOW!", literally ran to the phone and within seconds we pulled out of approach and made a turn toward downtown. The pilot came on to say rather non-chalantly that we would have another go at it. I doubt the novices kept their jobs.
