The US president has the best culinary staff at their disposal for anything they can think up to have prepared for them.

Nixon still liked his cottage cheese and ketchup.

George HW Bush was excoriated for not knowing about bar codes at supermarket checkouts because of his lack of connection with economic realities.

If Trump has achieved anything, he probably knows more about fast food menus than anyone even close to the low end of his alleged wealth. Bad fast food at that.

Funny story. Decades ago my late brother was at the Kentucky Derby and ended up chatting up one of the daughters of the Hunt brothers, big silver investors in Texas.

It came up in the conversation that father Hunt's favorite food was McDonald's.

My brother questioned later whether the young woman was really who she said she was, but received confirmation upon seeing a documentary where the Hunt brother McDonald's fascination was mentioned.
