First off all do not waste the time of the salespeople. When you enter a store with the sole purpose to scout through the racks and you are approached by a salesman explain that you are just looking through and that if you need assistance you will call for him. This way you will let the salespeople to take care of other responsibilities of theirs instead of wasting their time.
Don’t pressure the salespeople in the store to immediately pay attention to you. Instead wait until one of the employees is free and approach him on your own. On the other hand if you require special assistance while shopping, pick up less busy hours of the day for your shop visit thus you won’t have to bump into the high traffic of customers when everyone has a question and seeks the attention of the salespeople.
Don’t underestimate the usefulness and knowledge of the salespeople. A lot of people don’t realize how helpful vendors can be if they are simply approached nicely. For example if you have entered a hardware store and you are looking for a truck mounted carpet cleaner don’t be reluctant to ask the employees of the store for help. They will most likely show you the best truck mounted carpet cleaner that you can afford and even more they will turn your attention on the cleaners that are sold at a discount at the moment.
Never trash the racks of a shop by randomly placing the items that you have picked-up but you’ve suddenly lost interest in. Even more return the items at their proper places. This will be much appreciated by the salespeople and they will be more willing to help you find the products that you are looking for.
When you start a conversation with a vendor be polite and ask him about his day, his family and etc. This will create a bond between you and him which will ease your communication an fruitful conversation.
