Had a funny thing with this not too long ago.

Was on a DL flight to France in EC.

Asked for a Woodford, FA asked "it's on the back of the cart. I'll pull back and can you just grab it?"

I did and she went on.

2 weeks later, same flight, same woman, exact same scene.

I said - you know we did this exact thing 2 weeks ago?
She smiled - I thought you looked familiar!
