A long time ago I spoke with a scheduler about the questions because I was confused that the guidelines said to ask about something, but there were no questions on the report about it. I was told the guidelines were outdated and I didn't need to ask a question, just to ask where something was located, so that is what I have always done. Oddly, they recently updated the guidelines and still didn't remove that section.
My problem is asking where something is, which is mandatory to see if they will escort you. You have to make sure it is something they actually have, but not something that is so close that they wouldn't need to take you, or something so obvious that your request is ridiculous. I would love suggestions.
Also the greeting quote--almost always I have to speak first and there is no greeting! I've learned that isn't an acceptable answer on the report so I find I have to manipulate some sort of greeting. So, instead of "excuse me," I've started going with "hello," because normally they will say hello in response.
I used to take the shops occasionally when the bonuses got high, but now they get taken for $8 and it's just not worth it to me.
