Girl at the bar asked me to buy her a drink. Was she interested or playing games?

Some random girl at the bar came up to me and asked me to buy her a drink. She told me her and her friends go to the same bar. Anyways later on that night I took her and her friend to the other bathroom because the 1st one was locked, and she asked me to guard the door. Why would she do this was she interested or playing games?
