I once went into a Walmart and walked up to the register with a box of donuts. As I approached the register, I noticed a lot of black specks inside the box, and they were moving. It turned out that an entire colony of ants was living inside the donuts. I showed it to the lady at the register and she took it, looked at the ants, and muttered something like "that's the third time this week" under her breath. I refuse to buy Walmart food anymore.
tl;dr Found a colony of ants in Walmart donuts; turned out this had been happening to people all week and they were still selling them
