If people decide to do business with you, say thank you! With the numerous options available in all retail and service areas, people do have choices, so if they decide to trust you with their sale or business, always show your appreciation by saying thank you.
Some businesses show their appreciation (if the transaction is reasonably-sized) by sending flowers or treating clients to a bottle of wine or a box of chocolates, which are lovely, thoughtful ideas. People love to receive gifts and, more importantly, appreciate being acknowledged.
Ensure you thank every person who crosses paths with you. It takes no time and minimal effort, but will show people that you do care and appreciate them. It’s a small and easy gesture, but one that is often forgotten.
