Response from Francesco
They where 4, all from 1 group. 2 of them they where arguing, infact the husband walked for all the tour 20 steps in front of the group. The atmosphere was very wierd and lots of tension so i finished the tour in 2h30' minutes as schedule, no extra like i always doing. Also no one of them could really understand english and been very difficult to understand what they wanted to do or what they where interested for.
