Creepy situation - How did I handle it? OPINIONS PLEASE?

Okay, so me and three of my friends were on the beach today, and we were setting up our towels and such. And then I saw this creepy middle aged woman walking on both feet towards us, very unsteady. I thought she was just being really creepy, but she came up and made conversation about the bathing suit cover that my friend was wearing. I thought that this was all she wanted to ask about, but she began to go into detail about how she had been robbed the night before, and then she told us that the ankle I had just seen her walking on was broken. At least that's what she "thought". It became very apparent that she was heavily intoxicated. She was slurring her speech, and she was just a mess. I told her I was sorry about her situation in an attempt to sympathize, and she just sort of stared at me. I wondered what she wanted, and she told us that she wanted to go over to the lifeguard station to talk to them about it or to get help, which was halfway across the beach. She told me that if I would help her over there that she would give me a "buck". I was very nervous, she was clearly drunk, and EXTREMELY creepy, and I was beyond uncomfortable with the idea of going off alone with her. The beach was fairly desolate as it was early in the morning. After I told her that I'm not allowed to go off with strangers, she called me "gay as ****" and called me a "************". With this, i went off on a string of profanities, and basically cursed her out. I feel like she deserved that part. But all I'm asking is for your opinion, do you agree that it sounds like a shady situation, and that I was right in not going with her, or does it sound like she was actually an old woman in need of some help? But if that's the case, then why would she be going to acquire that help so heavily intoxicated? I'm just wondering what everyone else thinks, thanks (:
