How would a catering sales manager handle a mother and daughter making arrangements for the daughter’s wedding differently from a meeting planner from a major corporation wishing to get a quote on a regional sales meeting, which he or she has already done in five other cities?

By being more Affable

Explanation:

A wedding is a very personal experience that a lot of people look forward to and don't want to be disappointed. In this light, the Catering Sales Manager would probably be very personal with them. Very good natured and affable to ensure that the experience is a good one for the bride to be.

They'll likely pay more attention to detail and make suggestions that they think would work best to ensure a great day. As earlier mentioned, weddings are deeply personal. And so they require a personal touch.

The Sales Manager however will not be as personal with the meeting planner. Not necessarily out of disrespect but because the person already knows what they are looking for and so they will probably engage in a formal tone. There is also the fact that such people might be remarkably busy and would not like to waste time in personal conversation.

a.   is the correct choice.

good luck. : )
