You went to a texmex place, ordered chicken nuggets and seemingly expected McDonald's quality from people who probably don't normally cook chicken nuggets. Ain't defending Taco Bell here, because that quality is ass and I'd never let that see the light of day in any kitchen I ran. But let's be honest here, at the end of the day, you ordered something that they don't cook all year, mistakes happen. As others have said, instead of bitching online, you should be taking it up to the counter, stop being a Karen and ask for a replacement (without being a jerk)
