It was a company sponsored cruise to reward salespeople that made their goals. She was a co-worker that had a reputation of always doing things her way. I was not her boss, but was in charge of booking three private tours on the cruise. She and two of her friends during our stop in Pisa, were busy shopping and stopped to get gelato. Once back on board, i asked her what time it was and what time she was told to be back on the bus. She answered both correctly, but said time got away from them. I told her in front of the entire group, that if it happened again on any of the other tours, that we would leave them. Which we did in Rome after waiting a little over 10 minutes. Amazingly, she and her friends got back in plenty of time on our tour in Malta. As a side note. She got fired a week after that for fudging some numbers.
