Babysitting

So I’m being paid 25 a day. This week I watched one of the siblings 6:30-4:30 pm and him and his sister 2-5:30 and today 8-5. I still haven’t been paid but would I be a bitch if I asked for extra the days his sister is here? She’s about ten but I provide everything, even clothes cause they never send extra. I don’t wanna step on anyones toes but wasn’t sure if it would be ok for me to ask for extra when the other sibling is here.
