If she is willing to ask for my number and meet me on my off days to chat, it is not a stretch to want to see what her motivations are and if they match my own. In our case it would likely be more frowned upon than firable. That's a chance I am willing to take if she is.
Also we don't really work together so she is not my boss. I just happened to help out for a short time. She may never see me at work again for all I know.
