The most expensive lunch of all time. After finishing a meal for $21.47 at a restaurant last week, former President George W. Bush ’68 and former First Lady Laura Bush left a $40 tip for waitress Leisa Smith. Later Smith tweeted a picture of herself with the Bushes with the caption, “Bush did 911 but he did me a solid and left me a hella tip #,” and the tweet went viral. The comment gained so much traction that Smith had to tweet out a clarification that it was intended to be a joke.
