Is AUTHOR wrong in the post ? POST : I got paid a really nice bonus, and told my Person that we should go out to eat that night to celebrate. Person picks a place- Not one I love (or even really like), but I mean.. It's okay. We've talked about this before, but Person loves this place so I bite the bullet and offer. It's a pretty expensive place, and this bonus means that it's one of the few times we can go out and afford it.  
We have a bottle of wine while eating, spend an hour or two there. I leave an -overly- gratuitous tip, because the service was justifiably outstanding and over-the-top (so not so overly-gracious? idk, been in the service industry, good job equals good tip. Full stop). We take a bottle of wine to-go home.  


Cut to a few days later, I have a couple friends over for board games. I open the bottle of wine that -I- paid for. We finish it.   


Cut to a day later. Person wants to know where the wine is. I say I drank it.   


AITA?
