Try obtaining a Time Machine so that you can experience the menu from when it was good.
The Grilled Stuft Burrito, Grilled Stuft Nacho, the volcano burrito and lava sauce, the 1/2 lb cheesy potato burrito, the enchirito, the loaded grillers, the double layer taco, the chilito.
So many good menu items lost to time
Could you not just change the ring tones of your contacts to something else and then have all unknown callers use the bad time ring tone?
