I getcha. You have a business, and you've got to do what's best for it. I got to thinking about "design" cake makers, and I suppose they have a similar dilemma. I'm sure a portion of your clientele are aware of the difference. Funny thing, just now I was watching "Fabulous Cakes" on TLC, and they offered the client 'taste tests' of different flavor options. I assume you do something like that.
I do think in a restaurant setting, the experience there would be different. Their buying for themselves and for one, not for dozens.
