Is it normal to receive a tip/gratuity for a cake, in addition to what you already charge?

I had a customer who was so happy with her cake, give me an extra $20. It was an unexpected and pleasant surprise.

I have a client that gives me an extra $10 every time I make a cake for her...you are right, it's a very nice surprise!

I almost always get a little extra! And Im always so greatful! I just seem to get the nicest ppl!
After reading all the different post recently about how mean ppl are - I feel even more blessed!
I dont know if its "normal" but it sure is nice =}

I have some people that always give me a tip. At first I told them not, but then I released it's like when I tip the pizza delivery driver, so I'm more comfortable taking it when it is offered

I have one girl friend who always pays me $10 more than I ask her for. Other than that, no one else tips me. I don't really expect them to, though.

I rarely do but don't expect it....a few times they haven't had change and told me to keep the extra $5-$10.

Last weekend I received a $15. tip. Today I was given $100 for a $65 cake. Nice, very nice. Very unexpected!
