I was assalted at a Denny''s Restaraunt by 4 men who harrassed me and I asked the waitress to call the police but she said no she would not

Generally speaking, you're raising issues that are governed by state law and I practice in New Jersey.  Having said that, as a patron at a business establishment Denny's likely had a duty to take reasonable steps to protect you against foreseeable harm from a third-party patron who was presenting an obvious danger to you.  You should contact the local personal injury attorney.  After discussing the facts of the attack with him he should be in a position to tell you whether you have a viable litigation.
