A tour guide is having a difficult day the group he has to lead is not very easy to deal with to be fair it is not the group, but a particular person. A rude tourist who everyone's experience wanted to sour, did not seem to understand that he was a tourist, not a city guide.
Luckily for our weary protagonist, the rest of the group was sensible, preferring to follow the one who knew how to get to the expected destinations rather than a person who pretended to know more than the individual whose job it was to guide. At one point the stubborn man did not want to follow the assigned guide.
