I did one of those shops yesterday and one at another location two weeks ago. I don't have any problems with the instructions. At these stores they expect, if everything goes as it should, that you will be greeted almost immediately when you enter. What the instructions actually say is that when you are initially greeted and asked if you need help or looking for anything special, you say you are just looking. They want to see if the employee says "okay" and walks away and ignores you the rest of your visit or if they walk away and help other customers but they return to you and check on you. Even if you are "just looking," they are supposed to return to you and ask something like "still doing okay?" or "did you have any questions?" or "did you see our sale items over here?"
or something like that. They are not supposed to ignore you just because you are "just looking." When they return, (or if they do not return you go ask for help), you do the second part of the instructions and let them help you. If you do not do the instructions in that order, you defeat part of the purpose of the scenario so it is not okay. This is a very easy scenario.
