Haha, I know most folks just wear the t-shirts, I was being funny. But really with those hairy armed folks I think shaving or a jacket should be a must, in fact, I am almost certain that a food inspector would insist on it. I say, what about armpit lengthed gloves, haha! Many of the grocery stores here actually do get their icing pre-coloured Aunt-Judy. It is likely something that varies a lot.
I agree that there are folks who do beautiful air brush designs, I also will add candies or other edible decorations and sometimes non-edible ribbons and such too. Sometimes the cake dictates what you should add. But I have also seen the cakes that are referred too, where things are just slopped on.
I know a lot of folks who have never eaten anything other than a grocery store cake. In fact they are so used to them that they find home made cakes and icings, taste strange to them.
I have an order to do where the lady requested a non-sweet icing like a certain chain here uses. Now personally, we find this icing to be the worst one around, but apparently she likes it. So I will be making up an icing that will hopefully come out similar to it. I am just dreading it. Personally I find it very sweet, but it just goes to show, it is all what you are used to. I really wanted to tell her to buy her cake from that store, but since it is a friend of a friend, I don't want to offend her.
But I have had neighbour's children that thought homemade cakes tasted weird. These children would also likely not like homemade soup because it wouldn't be as salty as canned - which is what they are used to.
I think the comments are dead on about educating the public. I liken it to furniture. For example, Bombay company makes nice looking furniture, a lot of folks think it is quality furniture. However because of the types of woods they use and the way they put the finishes on, this is not furniture that will withstand the tests of time It looks good new, that is true, but it will not hold up the way Ethan Allen or Gibbards, (if you are a Canuck), will.
