New Bus Driver

[Rondy]

A Bloke turns up at the local bus depot to start as a driver. He's shown how to change the numbers and destination signs, how to operate the doors, and how to issue tickets on the machine.
"Ah, I never had to do the tickets the first time I worked on the buses, I always had a conductor on you see"
"Well Mr.Kelly, times move on, and all our buses are one man operated to keep down costs"
Satisfied with the explanation, he is taken out around the local routes, so he knows where he's going when he's out on his own.
The big day arrives, and he sets off for the first time on his own.
Twenty minutes later, the police ring the depot asking for a tow truck. The controller gets on the radio to Mr. Kelly and asks why they need a tow truck.
"Sorry boss, the bus is halfway through B&Q's front window, and they need the tow truck to pull it back out"
"WHAT THE HELL HAPPENED?"
"Don't know, sorry boss, I was upstairs collecting fares!"
