I used to slang some za on the side. The cash wasn't fantastic or anything, but it was some extra cash in pocket. But the wear and tear on the car just wasn't worth it anymore.
I think some of it depends on the place you work for and location. The joint I work for is an independently owned "franchise" in this area. I am at the Geneva location, but there is a St. Charles and a Batavia location also. I know the way they run the deliveries at STC is different than how we do and I hear grumbling from some of their drivers.
At ours, we charge $2.75/delivery. Of which, I get $2.00 plus the tip (no you dirty minded assholes...).
On an "average" weekend, for 8 - 10 hours of total driving, I can make $130 - $150 cash in pocket. On a good weekend, $200+
This past weekend sucked because of Mother's Day. I had 3 runs from 4pm to 7pm. But then all the sudden it exploded and by that time the day driver had left and I ended up with 10 total. And Saturday evening I also had 10.
On bad weather weekends we clean house. During one of those ice storms we had in December or January, I think I had a record 24 runs in one night.
For awhile I did the day shift on Sunday (I changed this past week because of my new role here at Sears frowned upon me working all day Sunday), and we would get catering orders. I made a $40 tip one catering order alone. One time delivering to one of the West Chicago fire departments, I got a $70 tip. A month or two ago for a wrestling tournament at St. Charles East high school, I had to keep going up there to replenish pizzas and I walked away with $50 something alone in tips. Other cool things I got to do was deliver multiple times to Elfstrom Stadium (where the Kane County Cougars play) and was in the broadcast both with them.
