In my experience, employees seem to have an uncanny ability to annoy me when I just want to browse, and avoid me when I want their help. Out of the last 5 times I've gone into a store hoping to get some help and advice from an employee, I reckon 3/5 they have ignored me until I found what I was looking for, or concluded that they didn't have it and just left. I've even put my hand up in the middle of a store, like I was in school, waiting for assistance because ther were so few employees around, or because after asking me if I needed help as I walked in the door, they lost interest in me, and decided to have a chat with their colleagues.
