You checked qualifications, fluency in the required language, references, license if required, the guide turned out to be excellent but your guests were far from satisfied, even annoyed. What happened is a classic mismatch: You forgot to check your guests before picking the guide! Back in the days of the 5-day 10-country group tours, it was simple and straightforward as what was expected from the guide was exactly what they had learn to do and did very well day in and day out. The same circuit: church, monument, statue, church again, another monument complete with accurate historical dates, names and descriptions. It was by the book, on schedule and flawlessly boring.
