"Wait until you get a job"
"Wait until you get to college"
"Wait until you get out on your own"
"Wait until you get out of college"
"Wait until you get a REAL job"
"Wait until you start your Navy career"

Generally a service industry job for some extra-spending money either after school or during summer break, but yeah, it's fairly common.
Back when I was in high school, the most common summer job was peach picking and packing. The peach picking season was right after school let out for the summer.
