I still think it's fifty bucks more than you had yesterday, it will put gas in your car for a while. Sure, you wish it was more, but it's still fifty bucks and you didn't work overly hard for it..
So let's say a woman runs a business cutting hair in her home. She charges $30 for a cut. You go in, get a haircut, and hand over $15. You say "hey, it's $15 more than you had an hour ago." Is that right? The fact that they OP's dd expected to be babysitting until only 8 pm or so, and had to stay hours longer, without notice, I would expect the couple to pay her more than her usual $10 an hour - what if she had made plans for that evening?
