Seems like most everyone has focused on the customer showing up early, when the title of the thread is the OP asking if an hour and twenty is a reasonable window of time for a provider to cancel....so if that is the question then him showing up early is irrelevant. She was gonna cancel regardless.
And the customer doesn't seem put out....
Massage Envy has a three hour cancelation policy, session to be paid if session is cancelled under that time....'course they're not giving me a bj in there either
