There are questions that should be asked but wont be and ones that could be asked but shouldn't be. It depends a lot on the persons, their relationship and the context where the lines are but if its just a bot you can ask anything. The answers would somewhat depend on your role but they wont depend on who you are or how few or how many questions you've used up in the last hour, today, this week, this month and this year. Humans are like that, we are like: I've never asked for anything! as if its an important metric.
