Line Time: May I Ask You a Question?

The 180-degree pass-by involves walking near the customer, saying ?Hello,? and passing by. Then, after three or four steps, turn around and with a quizzical look on your face say: 

MAY I ASK YOU A QUESTION?

WHY TO SAY IT
Usually the customer will then turn, take a few steps toward you and say, ?Sure.? Now’s your chance to open the sale: ?The buyer just ordered this model ? do you think we should order this other model too??
