Enhancing service: In this competitive society, the quality, function and packing of different products are almost the same, but service has no limits, so we can try our best to show our sincerity to customers so as to earn more fixed customers. For example, when customers come to our store, we stand beside the door to open door for them and saying welcome. In addition, when they come to wash dogs, we should firstly play with dogs and touch them softly in order that they can trust us when we wash them. All in all, we should pay much attention to the littlest things because sometimes these things can affect customers’ mood subtly.
