When we ask the customer’s permission and then ask our question, the probability that the customer will give an accurate and complete answer to our question increases.
However, many beginner sellers do not follow this obvious rule and ask different questions without the customer’s permission and expect the customer to answer all their questions.
Remember, if we don’t ask the customer’s permission before asking him a question, he will think we are like an interrogator trying to force some information out of him.

Steve, if you’ll allow me, I’ll just ask a few short questions and not take up too much of your time
Steve, if you allow me to ask you a few short questions to understand exactly what your needs are
Steve, if you allow me to ask you a few quick questions so that I can best serve you
Steve, if you allow me, I will ask you a few short questions so that I can recommend the best product for you
