The Customer is Always Right
The key to good customer service is to treat the customer as you would wish to be treated if the tables were turned.
Everybody is different and customers will have different aspirations, motivations and reasons for choosing your company. By understanding the needs of your customers you can achieve a higher level of customer satisfaction, continued business and a more enjoyable working experience. If you work in an area where tipping is common you will likely do better financially too.
