Thank you, Webant!
Dexter, it's frustrating that we have to make so many assumptions in this case, due to JR's lack of communication and forthcoming-ness

.... But he keeps saying that her priority was to get to an ATM. So I do think she had her own money. Just for some reason, she let her on-hand funds dwindle to 40 pesos. Why, I don't know. Obviously you don't want to carry a lot of cash on you whilst hitchhiking across a 3rd world country, but when in Mexico, you ALWAYS want to have bribe-cash tucked away, just in case. She was in the country for that long, I'm sure she knew this (esp after the shake down with the motorcycle helmet ticket). So I don't know why she let it get that low. I think he said he tried to convince her to let him get her a bus ticket. She supposedly said no, whether it was because she didn't want to pay for it, or she wanted the experience of thumbing it across Mexico, I don't know. But if he offered to send her the cash for it, perhaps it was the latter.
