Well, San Francisco is very very liberal.
Their local government has put policies in place which drive up the cost of doing business.
This is a result of S.F. policies which burden business.
The people their see that there is a price to pay for the costs placed on businesses.
I was there 2 weeks ago as my GF attended a medical convention. The prices for McDonald’s and Starbucks are almost triple that of the ones in L.A. We noticed it’s like the prices in the international airport at boarding.
