Wow, thats a cool story. You were lucky!
I remember when i was in vacation with my girlfriend. In Spain a few years ago. The Roomservice did a great job, but we are the people who clean the room before the roomcleaner comes (german style).
One day we did'nt want to clean up and we did hang the shield on the door "please don't disturb". We left the room for going to the beach and we believed that the roomcleaners would skip ouer messy room. But they didn't....they cleaned the room while we were away...and it was so fucking chaotic.... I was so embarrassing. We left a big tip the other day :P
