Mainly - obese people.
There was one woman who appeared to have a large tail trailing from under her skirt but as it is all taken out of context, she could have been en route to a fancy dress party. We'll never know.
The rest were extremely fat people wearing ill fitting clothes, going about their daily duties in a supermarket.
We know there are obsese people around here and in America, I think this youtube clip was taken in America.
Not a very kind film and, LR, haven't you anything better to do than voyeur on those less fortunate than yourself? If you or I were severely overweight we'd be able to afford decent clothes, the film was obviously of poor people who couldn't.
