Moonlight and Jupiter models are doing enough money from tips so I assume they won't bother to go with clients unless the fee is very high many clients there are from East Asia who don't have a problem to pay this amounts if they wish to get a boy from the bar. Personally I don't visit such upmarket bars because I am not willing to pay inflated fees and high price for drinks. It didn't happen to me but if a boy in apps ask me for 6k I wouldn't bother to reply and certainly a negotiation with him will be a waste of time.
