Don’t expect masseur to do anything extra if you are not tipping 100%-200%. Tipping 100% is not unreasonable if you want to leave happy.
Believe me, if you meet an attractive guy, you will definitely be more than willing to drain your wallet. There are guys who I don’t find attractive at the spas I’ve been to, so I just opt for a legit massage and leave a $20-$30 tip without all the extra stuff.
