TIFU by ordering extra chicken wings

I was ordering at the KFC drive thru and asked for three wings in addition to the meal I'd already ordered (which already had 3 wings in it). The young lady at the checkout apologised and told me there were only two left and when I offered to buy those, she told me she couldn't sell them to me.

I suppose at this point I should have seen what was coming, but I was too busy being disappointed. So I spent the rest of the interaction being surly (look, men my age don't sulk, alright. I was surly).

So I get home and unbox my meal and lo and behold, the young lady who I had been borderline mean to (I tried not to take my disappointment out on her but really should have tried harder) had given me the two extra chicken wings that she couldn't sell me.

I'm sorry anonymous drive through checkout lady. I'm a lot more grateful than I let on before I knew what you'd done.

TL;DR I ordered extra chicken wings which KFC didn't have enough of to sell me. Checkout lady gave me the wings she couldn't sell me despite me being borderline mean. I wasn't awful, I promise, but I should have been better.
