After reading this thread, I must say that I have never seen such rude comments from a customer. You went above and beyond the call of duty to give her a scratch cake and a wonderful design for a "much too cheap" price. She must be a very bitter person to attack someone like this. Just remember that "karma" eventually gets even!
I have seen several comments on here about how she must be a hateful person because she had to buy her own birthday cake. I probably have as many friends as anyone around and I have had only one birthday cake since my 50th birthday 8 years ago. I am queen of our Red Hat group and the first year I made a birthday cake each month for the members who had birthdays that month. Come July, we went out to a tea house for lunch and I was expecting a birthday cake. NOT...........Even the establishment did not offer to buy my piece of cake I got for dessert. I don't think anyone thought a thing about it. They are just used to me always baking for people. It really hurt my feelings. Needless to say, I have not baked any birthday cakes for our gatherings since!
Anyway, my point is to not think that someone is hateful because they have to bake their own cake. If I had one, I'd have to bake it.
Back to the subject at hand.........wish we could bombard her with our opinions like we did Sugarcraft.
Good luck in your move back to Australia. Sorry you had a bad experience in Raleigh. I was there last year for a wedding and everyone was so nice. I'm sure you just hit upon the bad ones.......Many thanks to your husband.
