Well, it started with the ceiling fan. We marched down shortly after checking in and announced that the ceiling fan wasn't working. For three days it still didn't work, despite me pulling all the chains. Then one day I found the switch for it that was hidden behind a lamp. Minutes after telling him about a ceiling fan that wasn't broken, I accused him of trying to pass off "old pesos" on me. You see, several years ago, the Mexican government converted all money from "old pesos" to "new pesos." All of our travel books warned us that old pesos were worthless-- 1000 of them are equal to 1 new peso. What the travel books didn't say was that Mexico stopped printing the words "nuevos pesos" on the new pesos in 1994. When the desk clerk tried to give me perfectly good bank notes that weren't marked "nuevos pesos," we thought he was ripping us off and demanded"nuevos pesos," much to his frustration. We took our $20 back and marched upstairs where we read that we had just rejected perfectly good money. We sheepishly returned downstairs after memorizing the Spanish phrase for "I'm sorry." The next morning, we demanded to know where our tour guide was because he was 30 minutes late. "That tour is at 10:00," the same clerk said. "Well, it's 10:30," we told him. "No it's not-- read this sign," he said, pointing at one of the little signs that were all over the lobby of the hotel-- signs that I had ignored because they were in Spanish. On the back, in English, it said that clocks would be turned back an hour for daylight savings. We finally understood why our 8:00 wake-up call never came. Two days later we tried to go to Monte Alban. That was the morning I became sick. With the help of the desk clerk (again, the same clerk) we rescheduled for later in the day since I was feeling better. Then later in the day rolled around and I felt much worse (see below), so with the help of the same clerk, we rescheduled it for the next morning, and both times we accidentally hung up the phone on the tour agent. He looked pretty glum all week, but when we checked out, he actually smiled.
