Is NOBODY wrong in the post ? POST : This isn't a long story, and there isn't much drama, but I feel it merits asking.

This started roughly a week ago. My roommate's parents are helping with some kind of horse race event or something (They are old money farmers) and my RM is asked to help out for some money. Also for context, it's important to note that, yes, we are tight on money, but aren't in trouble (Had to pay some extra bills and such)

I talk to his mother and ask her if I could also help, and when she says I could, i then proceed to ask how much I would be paid for it. She doesn't really take the question well, responding with "Why does that matter, I thought you were going to help?" 

I don't know what to think or do so I just tell her that I could use the money is all. Finally she tells me. She is offering $60 for the job. Keep in mind, this is an event that we would work from 7am, and the event ends at 6pm. Now I'm not against helping people, but I don't really feel like like working for \~$5.50 dollars an hour (I'm prone to heat strokes. I can work in the sun, but prefer to avoid it) So I tell her that I'm not interested.

She gets super mad at me, calling me ungrateful and such before hanging up. Apparently she also called my roommate, because now he's annoyed that I pissed off his mother and is asking stuff like "Why did you even bother asking if you weren't going to work?"

I don't feel I'm being unreasonable here, nor that I owe her my time really. AITA?
