Final answer:
The drawback of Andrew's primary objective is limited information, competitive pressure, overlooking smaller opportunities, and the risk of rejection.
Step-by-step explanation:
The drawback of Andrew's primary objective to crack an exclusive deal with the owner of the automobile showrooms during his first sales call is that it can lead to limited information about the owner's needs and preferences, resulting in an ineffective sales pitch. The drawback of Andrew's primary objective is limited information, competitive pressure, overlooking smaller opportunities, and the risk of rejection.
By fixating on a single large deal, Andrew might also overlook smaller sales opportunities within the chain of showrooms. Moreover, pushing for an exclusive deal too early may increase the risk of rejection and potentially damage the relationship with the prospect.
