Worker: Customer Service, Anthony Grant speaking.      can I help you?
Customer: I can’t believe this is happening! I called and ordered a 32-inch bag last Friday,       today I found that you sent a 24-inch one. I was planning to use that bag during our vacation in Mexico, but it doesn’t seem possible any more because we’re taking off on Saturday. It’s only three days away. What am I     (suppose) to do?
Worker: I’m really sorry, madam. I   (check) it right away. Would you please tell me your order  ?
Customer:       is CE29.
Worker: Er, just a moment. I do apologize, madam. There does seem to be a mistake. I’ll have the correct size bag      (send) to you by over-night mail right away. It shall arrive by this Friday. It will be    time for your Saturday trip. Again I apologize for any     (convenient) caused by out mistake. I promise it won’t happen again.
Customer: OK. Well, thank you.
Worker: Thank you, madam, for choosing Linch Mail Order Company. I hope you have     wonderful vacation.
