we went out last night for dinner. There was 8 of us inc my DC who are 2&6 and my sister, BIL, DN and BF. It was DN's birthday. We left early with the DC and my sister agreed to sort the bill and let me know how much later.
Today I got a text to say our share was £65 of a bill of £140. The DC's food was £11. On that basis as 2 adults DH and I have paid £54 of the bill which is over a one third share.
I will pay and won't mention it to her but it is typical that instead of deducting the DC food and splitting it 3 ways, we have somehow ended up paying £10 more than the others.
She is a penny pinching git I feel and am a tad irritated by it.
