Step-by-step explanation:
If this would be the case, I would appreciate my customer's concern of buying that new phone. I will take his all details, and will notify him as soon as the new mobiles reach my store. I would ask him patiently to please wait for few days and i would try to make to delivery as soon as possible. I would least likely to tell him clearly that the phone is not available at the moment and come some other time. This would be so rude of me. So I would most likely to take his details and inform him as soon as i get the delivery of new phones to my store.
