So we invited pils to ours, they suggested we all go to our local pub for Sunday dinner. We explained we couldn't really afford it and offered to cook Sunday dinner at home. Pils offered to treat us which was lovely so we said yes. When we arrive at the pub fil says "right our treat, you just pay for the drinks" So we ended buying drinks for us, 2 dd's and ils, then when food is finished dd's want pudding mil helps then decide but then doesn't go to order it (you pay as you go at this pub) so I end up going up. All in we spent £40 Aibu to say if someone says my treat they mean the whole bill?
