Great food topped off by a horrible attitude combines for a rather unpleasant dining experience.
For whatever reason, this Oregon based franchise does not seem to apply its standards rules to the Scottsdale location which may be best described as stuck in the 60's with its horrible attitude toward customers, refusal to take any kind of plastic card, and even its refusal to serve Splenda (which costs more than other sugar substitutes). Saving pennies at every corner may seem like a good idea for a business, but when it ends up disrespecting your customer base, not such a good idea.
The franchise needs to get this store in line or revoke its franchise rights.
