The Law of 250 was discovered by American sales guru Joe Gillard, who often attended the funerals of relatives and friends when he sold cars in his early years. Every funeral, joe girard found a rule that the number of people attending the funeral always fluctuated around 250. Out of professional sensitivity, joe girard believes that there are 250 potential customers behind everyone. If one customer says hello, 250 customers will say hello. If you offend one customer, it means that you have offended 250 customers.

This law tells us that under any circumstances, we should control our emotions and not easily offend our customers.
