[Q]: Person1: I Don't know how they do it ! Our competitors have undercut us by 10 % percent on the price of our latest model . There is no way will be able to compete against that . We're barely breaking even with the present prices .
Person2:These price wars are disastrous for our bottom line . If they're charging 10 % less than we are , we've got to find a way to lower our price while keeping our profit .
Person1: Profits are almost nonexistent now , we can't beat their price . How do they keep their price so low ?
Person2:We can try to lower our cost of production then . We need a price that we can compete with , something comparable with the competition .
Person1: You really think we can make it ? I don't have much faith in our ability to lower the price again . We're no match for them , the competition will beat us hands down .

[Q]: Person1: I need to know why I'm being charged $ 10 for a movie that I never ordered .
Person2:Hmm . Your file shows that you watched ' Titanic ' Monday night .
Person1: Monday night ? Monday night I was at a great concert .
Person2:Well , as they say , garbage in , garbage out . Let me correct this error , please .
Person1: Thank you . It's very nice when problems can be solved quickly .
Person2:When I deleted the $ 10 , the computer automatically added a $ 2 service charge .
Person1: Are you crazy ? You made the mistake and now you're charging me for your mistake ?
Person2:Sir , if it makes you feel any better , the $ 2 service fee used to be $ 5 .
Person1: Why don't you just stick a gun in my ribs and take everything I have ?
Person2:Unfortunately , sir , you'll have to pay the $ 2 , whether you like it or not .
