Car wash detailer and attendant.
My parents owned a automated car wash and I'd work weekends and summers either scrubbing the tires/rims and bugs off the front of cars before going through the car wash in hopes of a tip or do detailing of cars, trucks, boats, motor-homes, etc.
The detailing is where I made my real money.
My Dad let me keep 100% of the money from the detailing and it was completely up to me to drum up business, make appointments, etc.
Would typically make anywhere from $60 to $200 a day on a summer weekend.
I actually really liked it most days since I was my own boss at the age of 14, 15 and 16.
When I wasn't busy I'd take care of the lawn work there or pressure clean the building or empty out the coin vacuums, etc. Got to blast my rock music and keep busy all day without being overly worked most of the time.
This was when we were living in our "wilderness" years up in a very small down in the very center and right on the boarder of NC on the GA side. Town was called Hiawassee. Population was 2,000.
When we lived there in the 90's from '92 to '96 it was a blip on CNN news as one of the safest places in the country. Was literally one of those places where everyone knew everyone else.
Our house was maybe 10 mins down the road from there and at the age of 14 I'd ride my little 250cc Suzuki GN motorcycle to "work". I'd ride into town for lunch. At age 15 I started driving to peoples place of work and picking up their cars, driving them back to the car wash, detailing them and driving them back. It was funny to me at the time that no one but me seemed to even caution that I was only 15 and didn't even have a license. I'd always tell everyone and the typical response would be "what are you going to do, run off with it? We know where to find you, who your folks are".
Funny looking back at those times. I grew up in SE FL where there's no way stuff like that would fly and where I live now same thing.
Only a little place like that could those things be possible.
