Was invited by in laws for Christmas Eve dinner weeks in advance. They even invited my mom and grandma. They served us 3-4 day old meat from a dinner party they had days earlier. There was no new food prepared for us including even boiled vegetables being 3 days old. They are wealthy people as am I.
Are we wrong to feel disrespected by this?
You can easily make the case for both ways. Esp the fact that you were invited weeks in advance for the Christmas Eve suggests it was not to get rid of last minute left overs.
Also 3-4 day old meat - how did you know it was that old? Was it smelling? Tasted funny? It’s it decent then it means they took all precautions to serve you decent food.
Ultimately trust your instinct. There are no logic or rules you can use to determine this. Only you can know based on the sum total of your interactions with them.
