I wanted a birthday cake, but I have a soy allergy. This shouldnt be an issue though at a good bakery. I spoke with the receptionist on the phone and she was nice and referred me to someone she said would know. I asked him some basic questions like does it have soy flour vegetable oil and is it just cocoa based or what kind of chocolate it has. He said that it shouldnt have soy but he seemed reticent to say what was actually in the cakes. Then he said he didnt want me having any and he refused to sell to me! He handed the phone back to the receptionist who sounded stunned. If this were a decent bakery they would know their ingredients and use real ones like butter and cocoa. I mean if they would have just said "we use soy" I would have been ok, but to refuse to tell me and then to refuse to sell to me!? That's just jerky.
