I work at a laundromat every Sunday and for the past few weeks a disabled woman with sciatica has been coming. she needs help with virtually anything that requires movement, including loading her clothes into the machines, taking them out of her car, even standing up. at first i was very happy to help. she is very very kind and has offered to buy me food or give me pocket change (but i refuse every time) the first few times i had no problem helping her out; our usual routine is that i will see her, get her bags (always multiple bags) of clothes out of her car, get her a cart, load the clothes, and when she’s done help her stand up from her seat, take them back to her car.

the problem with this is that it’s beginning to detract from my work. any day she comes in i close later than i have to. the time i use in helping her i should be using to clean or fold or help other customers. like i said, she’s very kind, she said she’d call my boss and tell him how wonderful i am, she says im really a great help and that she appreciates me, and that she absolutely must give me something for easter. for that reason, i would feel awful outright refusing to help her again but my job description doesn’t include being her personal aid. how should i navigate this? wibta if I just said I couldn’t help her out anymore?
