I think that is a lot of the issue, people get fired after these events as can be clearly seen in the posts which isn't a bad thing.
As the days weeks and months past these emotions and initial enthusiasm settles down and in reality not a lot gets done.
They will always show you the examples of people who have immediately implemented some of the initiatives and gone on have super success, if they didn't they would not have anything to sell but in the main, most people just wait for the next 'big event' attend it again and so it goes on.
I agree that a lot if the stuff is 'Americanised' and does not cross the Atlantic comfortably one of those is the scripts which do not sit well with us Brits as they come across and are completely false and most prospects can see right through it and just do not like the American way of meet and greet, but I believe there is also a lot we can take out of it and adapt to British emotions.
We use a kind of script that those in the office 'loosely' follow that is British and works well for our customers, there are certain things in there that are a must that has to be followed but the rest is what the operator is comfortable with and this comes across in the conversation very well.
Our number one big no no, is they must never,ever under any circumstances argue with a customer on the phone no matter how frustrating or angry they or us might get/feel. You would be amazed how this very simple discipline once 'mastered' works. I know the American guru's will also mention this and no doubt Mr Partridge does but implementing this is very difficult if you are naturally a confrontational sort and defencive of your abilities and your work because you have to drop this attitude but once done it travels with you both in and out of work and improves your relationships again both in and out of work.
Once you remove anger and frustration from your daily life its amazing how much you can accomplish and even how much your health can improve.
Just one of 'my' little nuggets some of you might want to trial.
