The second phase of the Pre-Approach is that of obtaining an interview with the prospective customer, generally known as "the prospect." In many instances the salesman is able to secure the interview by simply walking into the presence of the prospect, the latter being in full view in his store or office and no intermediary being present to intercept the approach. In such cases the second phase of the Pre-Approach is passed over, and the actual Approach is entered into at once. But in other cases, particularly in the large office buildings of the principal cities, the prospect is found to be in his private office, and the salesman's advance is halted by a clerk, or even an office boy, and there are certain preliminaries to be gone through with before an interview may be obtained. In many cases, "big" men (or those who wish to be considered "big") surround themselves with so much formality and red-tape that it is quite a feat to run the gauntlet of the guardians of the inner temple, and much tact, diplomacy, presence of mind, and often strategy is required of the Salesman in order that he may "get at his man." Macbain, in his work entitled "Selling," says of this stage: "Between the pre-approach and the actual approach sometimes lies a trying time for the salesman. It is no uncommon thing for a prospective customer to keep a salesman waiting, either outside the office door and out of sight, or inside and in the presence of the prospective buyer. This is known as 'breaking the salesman's nerve.' It is often done with the idea of deliberately making the salesman nervous and consequently unable to make such an approach as otherwise would be possible. Perhaps one of the most common forms of this is seen when the prospective customer appears to be very busily interested in something at his desk and allows the salesman to stand an indefinite length of time and then turns suddenly upon him. This is especially disconcerting to the young man, but the experienced salesman recognizes it as an indication that either the man is very busy and actually hates to take his mind off his work, or that he is afraid of being talked into something that he will later regret. The salesman consequently shapes his introduction accordingly and will in no wise be disconcerted by this attempt as it will enable him to study carefully the outward characteristics of the man whom he is about to approach."
