Move over SLURPEE®, here comes FRUTTI®, a new smoothie making machine. The invention was developed by Global Smoothie Supply, a Dallas-based company run by David Tiller, husband of local PR gal Martha Tiller. The first self-serve GSS unit was installed at the 7-Eleven store on Northwest Highway at Hillcrest. Tillers, I think you can plan your retirement party now. Just pick a flavor, add a little rum, and send out the invitations.
