[The Tip feature needs to be rethought and completely optional.]

I am a buyer. 

Whenever I place a gig, and the communication & delivery exceeded my expectations, I always leave a tip.
I recently had a gig, and was asked - as usual - to leave a tip. I did not feel inclined, so I opted out.
The system kept asking me 2 more times to leave a tip_or not. 

Then I receive a automated Email from Fiverr asking me to privately rate my experience. I shared my experience, and again I was asked a whopping 2 times to leave a tip.
I understand that Fiverr needs to make money, but I insist someone here from Fiverr is reading this.
If you-Fiverr keeps on asking so aggressively for leaving tips, where you charge service fees, I will deactive my account and use another platform.
I had it with your overly aggressive way of inducing a charge fee!
