We are deeply sorry that you did not enjoy the tour. You were the only attendants on this tour, so basically you got a private tour for the price of a regular one. The guide answered all your questions you had and gave you an extra infromation about Prague and its history in the tram and after the tour, because that is our standard. Yes, we sometimes schedule a new guides on our tour, so the senior guide sometimes answers the question of the trainee during the transitions between stops. On the whole 3 Hour tour the trainee politely went aside you both to have a cigarette.
