I was amused last night to see a couple at our hotel who seemed to share my sense of frugality.
They were sitting in the chairs provided in an alcove of the open-air lobby, a floor above the bar where a guitarist was playing Hawaiian music. They had pulled their chairs up to the edge of the alcove, so they could see down into the bar, and were applauding vigorously.
The man had a glass — it looked like one of the water glasses from the guest rooms — with an amber liquid in it. No inflated bar prices for him!
