How about a decent spoon and thicker napkins?
It might be me, but it seems that even as I pay more for a sundae, the spoons and napkin quality is going way down.
I've attended several of "Miami" Mike Spinelli's lectures, and he is one of the best teachers of small business that I know. He loves to show how saving even a small amount on "cost" or adding just a little to "gross" can add a lot to "net". His book on developing a nation's tourist industry has become a "must read" in vacation areas and would be vacation areas. Even he, cheap as he is, cautions that lowering the perception of quality can lead to disaster.
If you want me to pay 5 or 6 dollars for a sundae, please give me a spoon that I can scoop with, and a decent napkin to clean up with. JMO
