E.g there's a big cake arriving which can all be cut in to slices and shared between a group of friends.
However one person sneakily puts in a pre order to have the whole cake for themselves regardless and this can't be reversed.
When the time comes for this to be revealed to their friends they act upset and remorseful even though they knew exactly in the moment they ordered the cake it would leave the rest of the group without.
I just don't have the patience to be empathetic. So now we all need to pander to you so you feel better about your selfishness?!
Why do people think they can have their cake and eat it?! Pun intended.
