Yes ask the receptionist if you can meet her! Some girls can fake smile but that's the extent of their acting usually. If the girl seems like she's forcing herself when she's talking to you, she's probably just trying to maintain the fake persona she's giving you but if she can't talk to you for a minute in it, she won't be able to keep it up in session. If shes curt or passive, then you know right there you don't want her and you haven't wasted all your money!(unless you're into that kind of thing lol) and if you want to meet all the girls, you have that right. If they give you a hard time, they don't deserve your money. Sometimes the person you thought you liked least turns out to be your favourite and you might choose her and have a great session. Anyway moral here being, I understand how it might be a little uncomfortable to ask to meet the girls but if you're looking to actually enjoy the girls company and you're not sure you will, its your money. Don't just throw it down a drain and don't let them try and convince you to throw it because they don't want to put in that little extra effort of talking to you.
