Interaction with Clothing Sales People: First Contact

Living in Germany, California and Hawai'i plus traveling in four additional states and sixteen countries have introduced me to very different experiences with sales people. Actually, I feel I was exposed to the whole spectrum from the sales person showing no sign of attention to my presence in the store to immediately addressing me physically, energetically, and verbally.

It is different from culture to culture what is considered respectful. Letting the customer browse without a friendly 'May I help you,' can be interpreted as rude just as asking right away. I used to take the sales person's behavior personal and judge and interpret it. Now, I try to simply observe.  Example: This person is probably having a private conversation on the phone and does not want to be interrupted by a customer. (Here I am assuming and interpreting) This sales person looks so bored. (Here I am judging and assuming.)->

This person is focused on a phone conversation. This sales person is standing in the store. 

Before I enter a store I assess: Do I need or want the help of a sales person. If yes, I go towards them. If not, I scan for the location of my objects of interest and the whereabouts of the sales person. I greet the sales person depending on the distance with a nod or a verbal hello. Then I send out the message psychically and/or verbally: First, I would like to take a look around. I will come to you/look for you, if I have any questions.
