I have a parent who for the past 4 weeks pays me a few days late. Wasn't really to much of a problem but now it's Christmas and with dreaded January looming, I could do with the money being on time. I did drop a few hints this morning when she said she'd pay me tomorrow.
We agreed in the contract to pay me in advance (every Monday), but at the time I never included a late payment fee.
What can I do without seeming rude?
