I was just reading through this thread and was thinking exactly the same thing.
Where are all the mechanics, waiters, hairdressers, check-out chicks (or should that be persons?), or garbo truck driver?
I guess they would now be:
mechanic - combustion administrator
waiter - food services consultant
hairdresser - follicle team leader.
ch-o-ch - inventory release manager
garbo - district environmental management team supervisor.
I'm a service supervisor... I look after the "Checkout Chicks and roosters"
And of cause the Customers!
