You never know if she is doing something on the side. She could have a regular or two, be on SA etc.
That said, as with the general advice here, I wouldn't be approaching her based upon past history and ask her if she's up for some fun.
At the very least, maybe a hello and see if anything, over time, comes from that.
No idea if she would still recognise the op, and either be freaked out, or what around him.
