I understand it's like an extras strip bar, and I've heard of drinks in exchange for conversation where the girls cash in their drink amounts at the end of their shift for a percentage or the total cost of drink. However, just because they're not indulging you in finger banging during this drink/ conversation stage for no additional cost, doesn't mean they're going to be horrible and prude in the session or whatever upgrade they provide. I hope you at least tip extra on your 'try out.'
