Creating rappot is very important to keep a business running. By doing that i don't mean you become a nuisance to everybody by being to chatty or too noisy. It's good to indulge customers when your serving them, that way you will get to understand their needs much more, and they will in return want to know more about your business. They will also feel comfortable and free to ask questions. If you do that, you will find people just flowing into your company with recommendations from previous customers just because of the first impression that you created when they first walked into your premises. Patience is a virtue when it comes to business, sometimes customers can be a pain, or irritating like asking questions that are so obvious, but you as the seller have to be very cautious in the way you handle such. Be patient, and calm, don't snap give yourself time before you answer them, and that way you will win them over.
