You all know that before ou start working for Mac Donald's or any other outlet dealing with clients and customers, when you are training to be a cashier at Carrefour or Waitrose, one of the main teaching is SMILE.
Smile to your clients, be polite, welcoming and do your best to help them.
I suppose that before being hired at the French Consulate in London, civil servants are taught just the opposite.
-Try to be as rude as you can do to your customers.
-Do your best to be as unpleasant as possible.
-Let them forget that you are supposed to be at their service, paid by the people of France, and impose upon them an attitude of superiority, you are the civil servants working at the French Consulate of London after all, and they are here to demand some service to you, a new passport for example, and the customer must understand that you are kind enough to do the work for them.
