To be upset with a work colleague of mine?

[Sparklyblue]

A colleague of mine is getting married today. Rewind to about 9 months ago. I was talking about making some cupcakes for a friend, she said she wanted some for her wedding and would I do them for her, she said she would see me right.
So Thursday came and I made 144 cupcakes from scratch, mixed them, baked them etc, my oven was on for half the day. Friday I lovingly iced them with buttercream and decorated them all with lovely decorations that I had made. ( Now I usualy work Thurs and Fri so had to take time off work, which I could have used at Christmas a my birthday)
She phoned me Friday and asked when she could pick them up and how much the ingredients cost. I told her this.
When she came to pick them up I helped her put them in the car. She came back in and handed over the cost of the ingredients and that is it.
Also she had these beautiful cupcake wrappers, she sat down, handed me half and started putting them together, like a mug I helped her.
AIBU to be upset that my time and electric means nothing to her, I am actually out of pocket. ARRRGHH

YABU. Are you a professional cake maker? No? Then it's a gift. Yes, 144 cupcakes later you're probably not feeling too generous, but unfortunately I think it would be rude of you to ask her for more money, even after her honeymoon.

YABU. She didn't ask for receipts, you should have included the electricity if you weren't gifting that to her. She probably assumes that the labour is a gift and you should have put her right about that if it isn't. I do bake and I am that it has taken 2 full days so I'm not surprised that a non baker wouldn't have known that.
