When I was in high school, I worked for a family friend who owned a garden supplies company. He put me incharge of assembling and packing soil pH testing kits. Sat in the workshop, listening to the radio, inhaling all kinds of crap while making those little kits. I wasn't even allowed to change the radio station...
Later, while I was at University, I had a job sitting behind the counter at a quiet little Gas Station. I worked the late night shift, never got robbed and the store policy was for staff to take their pay (cash) straight out of the register! I just used the hoist to tinker on my car and over summer I re-did all the suspension bushes on my old Volvo-beater.
