I have been to plenty of mcdonald's in US.. there are very few clean, and the vast majority are pretty brutal .. I am not a racist guy but if you think mc donalds hires mostly whites and latinos .. 
go to your local ghetto and snap some photos then try to convince me with your white latino sparkly new micky dees
I never said that McDonald's hires mostly Latinos or whites. I don't know what their hiring demographics are. But, In many areas with with a sizable Latino population, it seems that one of many places that will start off work are fast food joints. This is also true for many an American youth, of any race. If fluent in English, the front line (cashier) if not, then in the back. From observation, mostly females. And the 4 McDonald's in my area have mostly Latinos working there.
The McDonald's in my area are clean, with revamped designs. If you read the article and took a look at pics that I googled for you, then you would know that in certain markets they are revamping the restaurants for a more upscale look.
