Mom , look ! My first piggy bank and it still has money in it !  That is a blast from the past .  Remember when I used to beg you to break it so I could go buy ice cream ?  Yes . You sure have come a long way in valuing your hard earned dollars .  Thanks for not giving in to my childhood tantrums , mom .  But what are you going to do with that pig ?  I think I'm going to keep it as a monument to what I've learned about money .  Who knows , maybe one day he will sit on the desk of a top CEO in a major corporation ! 
Yes

Is there anything I can do for you ?  Would you please show me that mural ?  Certainly . Here you are .  It looks so beautiful . How much is it ?  Four hundred yuan .  That's a bit more than I wanted to pay . Can you cut the price down a bit ?  I'm sorry . Ours is a fixed price shop and I can assure you this is the best price you can get for a mural like this .  Maybe you are right . OK , I'll take it .  Well , I'll have it wrapped for you .  Thank you . Here is four hundred yuan .  Thank you . Please come again . 

Yes
