Please forgive me for the slight drift ........a lot of these comments sound like the customers we get where I work, so it is not only on board aircraft when people leave their brains behind!!
Typical conversation:
Customer: I've got an appointment with someone in the service department.
Me: What's the name please?
Customer: Well I think his name is Nick.
Me: I meant what is your name!!
............................................................ ............
Caller: Are you BMW?
Me: No we're Mercedes-Benz.
Caller: Well I need to speak to BMW. Can you give me their number??
Me: Er, sorry, no. I'm afraid I don't have it. (Thinks to oneself: do they think we are directory enquiries?)
............................................................ ..............
Customer: I've got a Mercedes car.
Me: (Thinks to oneself: well what a surprise, we don't get many of those in here!!
)
