1. Taking the rate without the table
Covered on the commission page. A rate that does not clear your rent is not a rate, it is a hobby.
2. Sizing the float for a quiet Tuesday
Then closing at two in the afternoon on the first of the month, which is the day that pays for the quiet Tuesdays.
3. Letting the helper handle cash without a count
Not because helpers steal. Because without a count at handover, an honest mistake has no owner and the argument poisons the arrangement.
4. Keeping records only when something goes wrong
Records written only after trouble prove nothing. The value is in the ordinary days that give the bad day something to be compared to.
5. Treating the float as profit
The most expensive one. Money in the drawer is working capital. Spending it feels free and shows up three days later as a counter that cannot trade.
