What was your worst restaurant experience?

Back in the early 80s my ex-wife and I went to a Waffle House, were seated and ordered our meals. The waitress brought our salads and drinks and said our meals would be ready shortly. After about 15 minutes or so she returned to the table and said that they couldn't serve us our meals because the Board of Health had just closed them down.....but there would be no charge for the salads and drinks. I almost puked wondering why they were being shut down.
