From my $150, I went home with about $100.
I worked 4 nights a week and made about $400 a week, plus wages (about $75 a week).
My apartment (3 blocks to the beach) was $150 a month. I was not complaining about either the minimum wage or the splits, as they all earned it.
I bet the system of splits has not changed over the years.
