That snuck up on us and we sent our 1st grader in with a $100 bill and a note saying to only let him spend $20. The neighbor 1st grader asked us if we are rich after that...

They said big salaries, even onshore devs at banks aren't getting paid big salaries.

We don't use cash much, so the small bills get eaten up and we never really have an opportunity to break a $100
