Giving Dinner Guests a Bottle of Wine as Apologetic Gesture

I noticed my lunch guests, who told me they didn't drink wine in the early afternoon and had turned down a glass of  La Crema Chardonnay I'd chilled for them, sort of playing with the food I served them, pushing  around the pieces of sweet potato on their plate the way that children do, as if hoping it will dissolve and disappear without their having to actually swallow any of it.  It occurred to me that my variation on the Nigerian Stew--an addition of kale instead of the ochre called for in the Moosebook Cookbook--was a deviation that only I found tasty.  These are kind friends who know how insecure I am as a cook, so I'm sure they were doing their best to eat it.  But at the end of our very enjoyable lunch (enjoyable because the conversation was lively and fun), I gave them the unopened bottle of Chardonnay.  It seemed fitting that just as guests bring a bottle of wine to thank the hostess, a bad cook should give the departing guests a bottle of wine by way of apology.
