In both cases, I think it's just smart business sense to send free minutes. When readers send free minutes prior to talking, it could potentially save a reader from receiving negative feedback if the two don't connect. If I wasn't able to connect with someone, but the minutes were free, I probably wouldn't leave negative feedback. If I receive free minutes after having a reading, am I more likely to call back if I'm sitting on some free minutes? Yup, I probably would! The bottom line, despite some sincere interests in helping others, this is a business they are running.
