package tour without coach

The bus stopped at Kings Cross, a group of passengers took there time to board the bus.

Then one of the passengers arrived on the top deck wearing what looked like a hearing aid over the next five minutes the top deck filled up with another 30 such people and last but by no means least a lady with a radio mike appeared on the top deck to  commentate on the guided tour.  Lets charge them a fee and take a chance there will be 30 empty seats on the bus.
