Excuse me , I have something to trouble you .   Yes ? I'll be very glad if I could be of any help to you .   An hour ago , I bought this vase with my tourist .   Oh , yes . I remember it clearly . Is there anything wrong with it ?   I'm afraid so . We found this crack on the bottom when I went back to my hotel .   Oh , how awful ! Let me have a look , I'm terribly sorry . It was most thoughtless of me . Would you excuse me , please ?
