Customers are always right. That's how it is in business since the very beginning. Without these customers, you can't sell a product and make profit. In business, the two parties that can benefit the most are you (the seller) and your customers. In dealing with customers, one should always be patient, considerate and open for some criticism or suggestions from them. Their satisfaction should be your priority, the products and services you offer are for them to purchase and utilize, so if they have complaints, work hard to improve those weaknesses of your business; if they suggest something, you can consider those and; if they have questions about the products, entertain their questions and answer honestly, do not exaggerate or make up information. We all have different ways of handling our customers but maintaining the good quality of our products and services will make them your regular customers and potentially bring more customers to your business.
