I was lucky enough to go to the Galápagos Islands on a small ship once, and the staff aboard had me figured out within a matter of hours. On the first day, in the evening, we had a welcome cocktail in the reception lounge. They had created two batches of fruity drinks and poured them into champagne flutes on the bar. I asked the bartender, "What are these two flavors?" He pointed and answered, "Only that one has alcohol in it." I grabbed one. He knew I didn't really care what flavors they were when more important factors were at stake.
