SF restaurant known for rudest waiter closes

Sam Wo, a 100-year-old Chinese restaurant in San Francisco once known for having "the world's rudest waiter," planned to serve its last customers early April 21. David Ho, a descendent of one of the restaurant's original owners, decided to shut down after officials demanded extensive health and safety upgrades.
