I haven't been doing this for a business, but have read lots of comments about couples buying a smaller wedding cake, and then ordering a sheet cake from Costcos or Sam's Club for the rest of the guests? I understand this is to save on costs, but it seems a wee bit impolite to me. What do you do? Do you ever offer to make the sheet cake for a lower cost? I know that if I were a guest at a wedding, and I saw the couple cut a fabulous cake, and then I got a gross fake frosting cake with chemical taste, I would be feeling like a second class citizen! If they can't afford to feed me, then dont invite me! Thanks for your input!
