I think you're right, it's CAKE.
The only thing I find strange is the "initial" order part of the PR. There's no question they ordered a couple units previously so that doesn't make sense to me. Were those purchases not actually purchases but tests?
Anyway, this is the best part of the PR:
"They had previously tested a system from one of our competitors and found our systems to be the clear choice over other available brands."
I wonder though, who might the competitor(s) be? From past phone calls with Michael, he seem to indicate that ESFS was really the only game in town when it comes to these types of units for the restaurant and super market industries.
