In this particular situation, it depends upon the education / "class" of the people you will be eating with. Brits have a particularly low opinion of American eating habits, but as long as you eat elegantly, and don't do the standard American switcheroo with the knife and fork all the time, you should be fine... but you MAY want to at least attempt to learn the other way.

I am married to a Brit and spend a lot of time there, and have noticed that table manners vary widely. I will warn you though that I know my father-in-law has decided not to do business with people based upon poor eating habits (held fork in right hand like he was holding a crank - fist and scooping action) - not the best reason to reject someone, but when you have a choice of people to work with these types of things can come into play. Your table manners are a hallmark of your education and upbringing. I too am right handed but have come to love the left hand fork technique, tines down, with knife in right hand - it's exceedingly efficient when you get the hang of it. You might want to practice at home.

I'm sure you will be perfectly fine with your current technique, but if you want to "fit in" and/or be looked upon as being adaptive, well-bred and educated, and of a higher standard than many American business people, I would suggest you at least make an effort to master the European way.

As many of us know, it is the little things that can set us apart and create a bond of trust and respect with other cultures. Being more "like them" can go a long way in developing warm relationships - especially with Europeans - and can reap you great rewards in other areas.
