The Party Warehouse interview questions

Management is around 20 years old, asking unnecessary questions such as where do you see yourself in 10 years from now? when they well know the position was temporary and I am well over 47 years old. Also what would you do if you had a customer at the till someone walk in the door and the phone is ringing, I said say one moment to gal at till, welcome new guest in the door and pick up the phone and say i will be with you in one moment please hold and finish transaction ....they were simply amazed with the perfect answer....well good lord, i have 20 customer service management i would assume my response would be a bit educated....
