the trouble with smoothie shop franchises as I see it is as follows,a pretty well known franchise operation in a city near me was ticking along nicely until a milk shake bar opened up literally next door,which low and behold sold smoothies too,and undercut next door just to rub salt into the wounds.net result,franchise up for sale.The way I see it almost anyone can get a cut of the smoothie market,for minimal financial entry,cafes,bars,kiosks etc etc,they can all eat into your pie.In the case of the franchised store above,when your rent and rates top 50k before you start,any ME TO imitators taking only a smallish percentage of your sales will often prove terminal.HOWEVER,if you are interested in selling machines,juice etc, as bolt ons to existing cafes etc,then there is probably some short term money to be made.just my opinion for what its worth
