It's so trivial but I often wonder what the "socially acceptable" thing to do is if someone brings cakes when you invite them for coffee. I always have a cake or biscuits or baking when I have folk round but should I be offering them the cake that they brought??
It's the same when anyone brings wine for dinner. Do you crack that open or keep it and serve what you'd already bought?
Eg...friend came for coffee last week and brought shortbread and lovely strawberries. I gave her the coffee and walnut cake that I had.
I know it's probably a case of going with the flow but is there a cake serving etiquette that I'm not aware of?
