I am assuming that they brought up her kids because she recently lost child support payments. Child support payments often don’t stop when the child stops being a minor if they are in university/college. The adults being in their 20’s lines up with finishing a degree.
The article also doesn’t mention is she works full time or what her position is
The article doesn’t say that she is full-time, but it does say that she’s worked 6 days a week for 19 years and that her position is “head cashier”. It’s the blurb under the picture at the beginning.
