I didn't read markos as suggesting you give a dishonest answer, hill. I read him to say

1. If you are willing to return the item, say so: "Would you like me to do that tonight?" - or something similar, suggesting a time when you could return it.

2. If you are not willing to return the item, also say so: "I'm really not comfortable doing it" was just a suggested form of words that says "I'm not going to do something I don't want to do" but isn't harsh and won't sound like "take a hike". It is nothing to do with dishonesty.
