I am white and was born in. Australia then moved to US and for the life of me I can't eat bland European food. I was invited for dinner at friends place who is British and they served me chicken. I took the first bite and couldn't eat more.
To be polite, I said sorry I need to use the washroom, came back and said I am nor feeling well and want to go home. They were concerned but I dont think they suspected anything. I went my merry way and thanked them for the food.
