Mr Mac
My experience and observations is that we have perhaps some of the best salesman in the world but delv and product are unfortunately a little lacking in man
Our salesmen (and women!!) may well be excellent, however so many of them, when confronted with a non-native English speaker are left with little alternative but to wave their arms wildly and shout very slowly in English! This puts us at an immediate disadvantage against our European brethren in many cases. My former German colleagues were usually fluent in at least two foreign languages, generally English, plus Spanish and or French and or Italian.
No we can all sit their high and might and say "everyone speaks English" but that simply isn't true, and people you are selling to are always more comfortable when talking in their own language. Talking "foreign" for any length of time can be mentally tiring.
Cheers!
