People need to remember you get what you pay for, even in the decorated cake industry. I've had to choke down a few of those "cheap", dry as the Saraha desert cakes and often when they see the guests as their function leaving half-eaten pieces of cake on their plates they learn this hard lesson.
THese cakes are the reason people seem to think "Oh people don't eat cake at weddings anyway." Makes me go thru the roof everytime I hear that! People don't eat BAD cake at a wedding; people won't eat cake if it is served too late in the evening and they've had too much alcohol (booze and cake don't mix well together!). People don't eat cake at a wedding if you wait and serve it after most people have left (leaving a lot of cake leftover, ergo the ASSUMPTION of "people don't eat cake ... we had SO much left!")
A wedding planner said to me once, "Debi, if I didn't already know how good your cakes are, I'd know it today. THis is the first wedding where I've helped clear tables and there is not one crumb of cake left on ANY of the plates!" This planner worked a lot of high end weddings so you can imagine what a great compliment is was to me.
People don't eat BAD cake at a wedding. Period.
