Thank-you with a smile is one of the most powerful words in the English language and in customer relationships. It is an expression of politeness between two people which creates a connection. Subconsciously it says ‘I respect and value you’. It sets the standard to begin a mutually polite conversation and keeps you in integrity. Said with 100% sincerity, it can overcome many obstacles. It’s like a bridge over a chasm of misunderstandings or a welcoming handshake inviting the person to a closer circle of friendship.
