3.2.1 Acceptable
(vii) Apps may enable individual users to give a monetary gift to another individual without using in-app purchase, provided that (a) the gift is a completely optional choice by the giver, and (b) 100% of the funds go to the receiver of the gift. However, a gift that is connected to or associated at any point in time with receiving digital content or services must use in-app purchase. 

 Perhaps you can try referencing Section 3.2.1 (vii) to respond. Chinese social media giant WeChat also has a similar tipping mechanism, and it has faced very similar review issues on the App Store. That resolved this problem.
