Answer:
No, the revenue should not be recognized in year 3.
Explanation:
In this case, the client has a right to return the Widgetron Deluxe (the product sold). Apparently the client isn't even convinced that he wants to buy it and consulting an astrologer and a groundhog on whether he should keep it or not is not something normal. Gil didn't even tell the customer the price of the Widgetron Deluxe which makes things even more messy.
Revenue from this specific sale should only be recognized after the right to return expires or both the groundhog and the astrologer are happy with it.
