In the 1960s, S.I. officially discouraged after-school jobs so that students would have time for sports, band, yearbook, etc. Among my friends who did work after school, there seemed to be 3 categories of jobs: casual, semi-real, and real. Casual jobs were things like dipping frozen bananas into chocolate sauce (in the '60s, there was a processing plant somewhere in the Sunset that did this), but most people didn't stay with it for more than a month or so at the most. It was a "buy new tires"/"pay for the prom" type of a job. Semi-real jobs were things like driving a VW Bug and delivering for a neighborhood pharmacy (Wakelee's on Clement Street comes to mind). Students who had a job like this often held it all through high school. Real jobs were those in which you might have self-supporting adults as co-workers. These included bank, department store, and grocery store jobs. In the early '70s, Bank of America's Travelers Cheque Department at #1 Powell Street (a highly seasonal summer business in those days), took on dozens of USF & Santa Clara students for summer jobs, while an S.I. face or two could always be spotted at the old Grand Central Market (now Mollie Stone's) on California Street.
