The smallest things may mean the most to people, if you know how. It may be snippets of applied technology, or it may just be an honest and sincere smile.
The Taiwanese are known for their warmth, often in small considerate ways. In this store receipt, there are some encouraging and motivating words for the customer (shared by an instagrammer). The words loosely translates to:
“Thank you so much for gracing our shop today. There is no persistent storm. There is no permanent night. Let us cross all crises with a smile.”
In terms of service quality, I would rate Taiwan and Japan tops.
Think about your customer service and processes. What small steps can you introduce that will endear you to your customers?
