I'd take whoever made the offer up on it, of course.
WWYD if you needed one ingredient to make a dish.....but the local grocery store was closed for whatever reason?
Depends on the ingredient. If it was a major one, e.g. you were going to make beef stroganoff but lacked the beef, I'd say make something else. But if you were missing a particular spice or if you were baking a cake and needed another egg there are ways to substitute for it. Of course, that also depends on what was missing and what I was making - if I was making chili and found that I didn't have any cayenne pepper I could work around it because I put a lot of spicy ingredients into my chili, like canned tomatoes and chili and a shot of medium heat chipotle salsa, so it would come out with some heat anyway. But if I was making a chocolate cake and was minus the cocoa, then I'd have a problem.
Oops, forgot the WWYD question:
WWYD if you were doing a family pedigree and found out that you were related to a criminal? For instance, you found out that Great-Great Uncle Fred was hanged as a murderer in 1870.
