According to Inside Edition
"A server got an unexpected tip from an unexpected guest. Rosalynd Harris works at Busboys and Poets, an eccentric eatery in Washington DC. It was the Monday after the inauguration, and the Women's March which she attended, when three men came into the restaurant and sat in her section. One of them was wearing a hat that said Make America Great Again and was in town to celebrate the new president. The big surprise came after the men left and she got the receipt with her tip on it, $450 dollars."
