Promptness: Promises for delivery of products must be on time. Delays and cancellations of products should be avoided.
Politeness: Politeness is almost a lost art. Saying 'hello,' 'good afternoon,' 'sir,' and 'thank you very much' are a part of good customer service. For any business, using good manners is appropriate whether the customer makes a purchase or not.
Professionalism: All customers should be treated professionally, which means the use of competence or skill expected of the professional. Professionalism shows the customer they're cared for.
Personalization: Using the customer's name is very effective in producing loyalty. Customers like the idea that whom they do business with knows them on a personal level.
