OK, glad I don't live there... San Fran banned plastic bags (which I always reuse for lining trash cans). Now they are banning paper bags. The concept is probably to force people to use canvas bags But the last time you did a $150 grocery trip, did you have 20 canvas bags to bring along? (See picture below) San Francisco looks to bag paper, not just plastic SAN FRANCISCO (AP) â In a city that has already banned plastic shopping sacks, there is a new target: paper bags. San Francisco Supervisor Ross Mirkarimi on Tuesday introduced legislation intended to encourage customers to bring their own shopping bags so stores can reduce the number of bags provided at checkout. The ordinance, if passed, would require retailers to offer a 10-cent rebate to customers who use reusable sacks. If the stores fail to comply, they could face fines from $100 to $500. Mirkarimi says the legislation would help save a chunk of the 14 million trees chopped down each year to make paper bags. The ordinance would affect some 135 large grocery stores and pharmacies within city limits.
