Greetings @humor0404, very accurate your post because people who own their own business or simply work for others, must maintain not only the image of the business or the product offered, but also their own image, be well presented, respectfully serve the customer, handle a vocabulary appropriate to the situation and most importantly know very well the product you are selling, this way you will succeed in your sale and the customer will return for another product.

Thanks for sharing this post.
