Is a bartender responsible for calling the police when they know there patron is severely intoxicated and at risk of harming themselves?

I was at a bar last night and was told to leave. The couple a few seats down called me over, who is friends with the bartender. They were arguing with me as to why I dont like the bartender and yelled I had threatened them. I went back to my seat and before I knew it the bartender pulled my drink from my hand and told me to leave. I was told they were going to call the police so I stayed in the parking lot to wait for them. I did not know how drunk I was until I returned to the bar today to talk with the manager. The manager said I was so drunk I was staggering, slurring, and dropped my lap top. After waiting a long time for the police to show up, I called 911 and they said there was never a call or complaint against me. As I was walking home I fell several times and injured myself. I know it is my own fault, but didnt they have a duty to call the police and stop serving me? If they did I wouldnt have gotten as hurt as I did.
