In a feast of special programming, NBC is celebrating the 50th anniversary of “Saturday Night Live” this weekend.

STUART, Fla. – It was just a regular lunch shift, but two Florida waitresses received the tip of a lifetime from one table: $850. Susan Morrison and Erin Gross were waiting on a Christmas party of 17 people on Wednesday at metro Diner. But when the bill was paid, the party decided to surprise the waitresses and each chipped in $50. The 59-year-old Morrison says she’s been a waitress for 40 years and has never had this happen. Treasure Coast Newspapers reports the waitresses fought tears as they hugged the woman who planned the lunch event.
