Still new to the hobby and honestly iv only been to 3 places lol, so far I have tipped $120 at 2 places but that was for 45 minutes at both (Not sure if increasing the time increases the tip for FS as well?) and the third place I tipped $100 for 30 minutes.
I feel like my procedure or negotiation tactic is off, do people usually ask what the girl offers and negotiate a price while getting the massage? I pretty much go in and before anything starts I will ask if they offer FS and if they say yes I ask them how much would it be, and this is the part that gets me, they ask me how much I would give and I usually say I don't know since I don't want to offer too low and they provide me with mediocre service and I don't say too high of an offer and be overpaying. All 3 times pretty much they gave me the tip amount I guess?
