(Poll question is about if you are feeling the same way.)
It happens pretty often in my case. They approach me and they ask me “How can I help you?” when I don’t ask them. Of course I respond negatively.
Well personally I dislike it actually, since I enjoy it more finding what I want on my own. I like it more when I go through every corridor in the store in order to find something. It’s more enjoyable that way. Plus I might find something else on my way as well.
