Please Help - 30 points!! A man approaches you at the customer service area of the grocery store where you work and shows you a note about a product pick-up. He signs something, and you understand he is deaf. What should you do?

A: Gesture "wait" with your hand, take his note, and check the computer or the storage unit in the back.
B: Kindly explain, using gestures and slow lip motion, that you will check and that you will be right back.

C: Signal to the customer that you will be right back, and rush from behind the counter to find the store manager to handle the situation.
D: Smile, read the note, and write on a piece of paper that you will now check the order on the computer or in the back and will be right back with an answer.
