Not McDonalds in general, but one particular McDonalds in Seattle is located at a spot with a large number of homeless people, where crime and open-air drug use is pretty common.
That is odd, I dont think there are any locations in the UK where there is open drug use. I also remember seeing clearly mentally ill people on the streets in Miami, something you dont see here ( though you do see homeless every now again - rarely tents ). Is that just a normal feature in cities in the US?
It's a normal feature of many large cities in the US, particularly those run by more progressive politicians. No city has adequate mental health treatment facilities or homeless services. Open drug use has been de facto decriminalized: elected District Attorneys refuse to prosecute and thus police don't bother making arrests.
I do support treating addiction as a health problem rather than a crime. But the current approach in cities like San Francisco is wrecking quality of life for regular people.
