Public Intoxication, Alabama

Question Details: I was taken to jail this weekend for public intoxication while waiting for a ride. They did not do a field sobriety test or a breathalyzer. I was not told my rights or even what I was being arrested for, the guy at the bail bonds place told me I should get a lawyer but I'm not sure if there is any point. Really what I want to know is when i go to court will I have to pay fines and how much are they? Is is possible for them to give me probation. I am also only 19, can they add a charge for underage drinking if they did not charge me when arrested? Important Notice
