Out for dinner a couple of nights ago.
Me and DP, friend and her BF, and another friend.
All paying for our own food.
I ordered a burger but didn't finish it all, so offered it to DP. He said Yes please, but let me finish mine first.
Immediately after that, friend said 'Oh could I try a bite first?' - she ate about half of what was left, then proceeded to offer it to her DP, and when he said no, our friend.
AIBU to think this was fucking weird? Me and DP were both a bit like, Erm, wtf to say something at the time!
