Hesitation: It is very simple to understand what this rule means. Only players must not stop their talk under any circumstances. Sometimes players make excuses to avoid challenges but very few excuses can be acceptable because hesitation is clearly noticeable for all listeners. Peter Jones is the one who habitually makes this issue and Clement Freud also makes his own hesitation with somewhat different way Peter Jones usually has done(I will show you later how it's different). Derek Nimmo's hesitation is very unclear. That is what we called as a terminal hesitation but Derek Nimmo personally doesn't want to be challenged with hesitation. That is why he often talks in an extreme hurry. Kenneth Williams is not a memorable player with this issue but he often dragged his speech longer than normal speed which means he wants to earn some extra times.
