It is often assumed that manufacturers & others will welcome suggestions for improved methods, usually accompanied by the suggestion that they ought to buy some new appliance, or employ the person making the suggestion to give effect to it. Different people regard such proposals in different ways, but usually speaking they are not received with favor unless tactfully introduced. It is thing to say, "You ought to buy that," or "Do so & so directly," & another to remark" Have you seen that? or "Would this interest you?" Of work much depends on who makes the proposal. If it be made by a firm of standing, with a well-established reputation for supplying, say, machinery of a positive kind, everyone in the trade will directly pay attention to the novelty, but if it be made by a firm with no credentials, the salesperson will must mind his P's & Q's if they wishes to secure a hearing.
Business relations are due primarily to mutual interests. Men who hate each other will usually put their feelings in their pockets if it pays them to do so. But much business is the result of appreciation or a community of interest in matters other than business. Plenty of years ago I knew a man who owed his prosperity to a gift for mental arithmetic. A customer with whom the firm they represented had never been able to do much business was so taken together with his arithmetical feats that they gave the firm the whole of his orders & thus laid the foundation for the traveler's success in life.
Mutual interests ought to be allowed to emerge in natural fashion. Ingenuity in dealing with a situation is a great asset. This is valuable when a person is faced with the necessity of 'finding employment or bettering himself. It is never that the applicant offers anything of special advantage to the employer. As a rule, they merely states the usual bread & butter qualifications of sort or another, & proffer devoted service. It may be said this ought to suffice. So it does if the employer has a vacancy, but, if there is none, obviously a special inducement must be offered. It may be said also that opportunities for suggestions are few. That may be so, but if opportunities are few the persons who take advantage of those available are fewer still. Practical initiative is very rare. This is applicable to large & small things. Few people can conceive & make a business. There's plenty of who can over it on & extend it.
When engaged on business of importance, it is useful to know something about the man you are going to meet, so as to keep away from blundering remarks. For example, a visitor calling on a Roman Catholic might occasion serious umbrage by an incidental comment concerning the Pontiff. On the other hand, the visitor, if himself a Roman Catholic would commit a gross breach of taste by remarking, "I think they belong to the same faith." Most people properly resent such obvious appeals to bias.
