What is the saying that if you offend a customer, it will affect your sales?

This sentence is: Behind every customer, there are 250 potential customers. No matter what situation you encounter, don't offend any customer.

The famous American salesman Joe Girard summed up the 250 Law in business wars. He believes that behind every customer, there are roughly 250 relatives and friends. If you win the favor of one customer, it means you have won the favor of 250 people.

On the contrary, if you offend one customer, it means you have offended 250 customers. This law effectively demonstrates the true meaning of "the customer is God".
