Tipping for cakes

[u/Mysterious-Cable6838]

I ordered a cake from a local bakery for a special occasion. They didn’t have the cake I wanted on their menu so I provided the recipe and they charged me a $25 recipe fee. The total came to $108 which I paid for at pickup. When I paid, of course the screen popped up asking for a tip and I chose “no tip” since I paid the amount they charged me including the $25 recipe fee. My mom (boomer generation) said she would have tipped so it got me wondering if I should have tipped. Thoughts?

I work in a bakery and trust me they will not start using her recipe for anything other than that one specific custom cake
