seems to me like you left our your cash. the girl helped herself to the $140 fee (which seems ok for the 30 minute session you got). some girls don't want to ask for the money up front and you having left it out, she could have made an assumption. she may have expected you leave the donation in an envelope when you come in, which is the usual protocol.
you then paid again at the end, she might have felt awkward about having already taken the funds. either way, don't call it theft. call it a mistake on your part.
