Excuse me , is this the right counter for express mail ?   Yes , it is . What can I do for you ?   I want to send some important documents to Canada for my postgraduate admission .   Are they urgent , please ?   Yes , the deadline for applying is 1st Feb , so I hope they will arrive in 3 days .   Well , DHL is famous for its speed and reliability . It is the fastest international postal service available . The document will arrive in two or three days .   Really ? But can you guarantee the safety ?
