Franchise Fads

Can I be an "I told you so" kind of guy for a moment?
My area, Cleveland-Northern Ohio has been in an economic slump for the past few years.
This makes me even more skeptical than I already am, when it comes to franchises that I choose to talk about with my local clients.
I will not suggest "Hot" franchise concepts to my clients because of my philosophy regarding "Hot" franchises.
Here it is:
"What
is hot is always temporary.Stick to the simple everyday products and
services that will not be affected by technology in our lifetimes."
Example:
A residential cleaning service franchise  is always needed, and there
will not be "robots" cleaning our homes anytime soon.
I received many phone calls in the last year and a half concerning E-Bay drop off stores.
Here is what I said:
"Forget it. This is a fad. E-Bay is not a fad, but it is not an everyday word {E-Bay} like it once was.
E-Bay is a great business model, but the margins in the drop off segment won’t make folks money.Again, forget it."   
The Pittsburgh Post-Gazette just ran this story concerning the end of the line for these "hot" concepts…
Drop Off Stores
I told you so.
