I wrote a letter to corporate, and included a link to the above photo. Needless to say, the woman who spoke to my husband today was horrified at the pitiful excuses for nacho cheese chalupas, and promised to send out coupons for a bunch of free stuff right away.
Honestly, I'd rather they take the time to properly train the employees at Taco Bell, so that in the future I and other previously-fucked-over customers don't have to hold up the entire drive-thru line to inspect each and every item ordered, to make sure that we not only received what we requested, but that each item has all of the ingredients and the proper amounts!
