If you are in the Thermae and you see someone you like, it is recommended that you don’t muck around. As mentioned earlier, the quality of the girls in this place varies greatly and the nicer girls get snapped up quickly. If you see a girl that you fancy, go straight on over and introduce yourself. Don't be shy as most girls will be quite happy to meet you. Once you have started talking with her, it's unlikely any other customers will come over and bother you or her, this sort of being against bar etiquette - unless it's someone who she already knows or someone she has been with in the past.
