Input:  Person1:     Hi , good to see you . What can we assist you with today ? Going away on business again ?  
 Person2:  Yes , I'm off again at the beginning of next week . I need to get some Traveller's Cheques .  
 Person1:      We do always recommend people take Traveller's Cheques when travelling overseas . The world is a dangerous place nowadays , you never know .  
 Person2:  Sure . At least if I do get robbed , heaven forbid , I can get my money back using the traveller's cheques insurance . Once , when I was travelling in France , I was pick-pocketed and not only did you replace my Traveller's Cheques for free , you also did it extremely quickly and easily .
