BROOKLYN - Carroll Gardens commuters say they're concerned for their safety at a local subway stop after MTA cutbacks prompted the removal of a manned token booth. The booth at the President's Street stop on the F and G lines was torn down this month. The MTA says it's one of many booths citywide that will close because of the agency's dwindling budget. The token booth was replaced by a customer assistance intercom, but local residents who frequent the stop say it's not the same as having an agent stationed there.The MTA says that the NYPD is responsible for patrolling subways.
