Guess a profession

I am a guy. When I am bored, I will go to this certain place to drink and chill out. However, drinking alone by myself is very boring and dull. So I have the option of getting this group of girls to drink with me. The girls only have to sit down next to me, chat with me and play games with me. And when I feel like it, I can hug them, kiss them and even caress them. In exchange for all these, these girls can drink all that they want. And if my mood is good, I might even take them out for supper. Okay so here is the question. What is the profession of these girls? =)
