Erin Carr-Jordan, an Arizona mother of four, received a letter from a lawyer informing her that she had been banned from eight McDonald's restaurants in the Phoenix area.

Why? Most likely because Carr-Jordan has made it her business to document filth at fast food restaurants ever since she lodged a complaint about a dirty McDonald's play area that went ignored.

Carr-Jordan, who's a university professor specializing in adolescent development, said she's found food, hair, gunk stuck on walls, and broken windows in several play areas. And, she claims, she's even taken swabs which detected infectious staph bacteria as well as other pathogens. Ick! Looks like the Golden Arches could use a good scrubbing.
