Wino was apparently smoking inside a restaurant when a waitress told her three different times that she needed to put her light out. After the waitress gave her a stern warning, Amy looked her in the eye and stubbed out her Marlboro Light on her cheek.
“She hardly flinched because she was so high. The whole place was open-mouthed in horror. The waitress covered her mouth in shock and just walked off to tell the manager. It was a shocking sight.”

This is what the Sun is reporting has caused Amy’s swollen mouth rather than Impetigo. I can totally see Amy doing that, but at the same time I do not know if that is what caused the Impetigo, or if she just got an infection from it.
Either way, she has a swollen cheek!
