Yup, European Butlers and drivers also do a superb job.
I've never seen an American butler! Or an American Gentleman's Valet either!
I can say that trained European waiters are a treasure beyond measure. I have only seen them in the most expensive restaurants that can pay for such professionalism. Paying people to be nice to you is damn expensive! Someone who can be paid to be nice is a rare find.
I heard the butler traininig schools in England have very rigorous training, being a butler is not as easy as one might think.
My friend who is coming from England later this month has a butler, FOURTH generation butler! He has two boys both training to be butlers!
