I am an engineer trying to learn sales and sharing this amazing story on sales and human psychology.
2 brothers, who used to run a tailor shop in 1930, used the most clever sales tactics to sell their stuff.
When the salesman, Sid, had a new customer trying some fancy suits, he would admit to a hearing problem and as they talked, he would repeatedly ask the customer to talk a little more loudly. Once the customer liked the suit and asked about the price, Sid would call out to Harry- his brother and head tailor, asking about the price.
Greatly exaggerating the response, Harry would say "For that beautiful, all wool suit, the price would be $42". Pretending not to have heard, he'd ask again to hear Harry say "$42". At this point, Sid would turn to the customer and say "Harry says $22". Many customers would hurry to buy the expensive suit and quickly run out of the shop with the "expensive=good" bargain before Poor Sid discovered his "mistake"!
The customers always left with a smile and a sense of achievement, blissfully unaware of how the brothers had used their sound understanding of human psychology.
