Starbucks magic

I have Starbucks magic. That means that every once in a while, I get a free drink. Why do I think I have Starbucks magic? Here's the evidence:

1. Approximately one week ago, I went to Starbucks to reload my Starbucks card. I ordered a grande coffee, and the woman told me it was "on the house."
2. A few days later, I went to pick up a coffee and had to wait, no more than 30 seconds, for the barista to finish talking to a co-worker. She apologized profusely for this and gave me a free coffee.
3. The next day the same woman gave me a free coffee for absolutely no reason.
4. Today I when I arrived at work there was a large Starbucks cinnamon latte on my desk. A co-worker had been given an extra one for free and she knew I liked Starbucks.

What does all this mean? I go to Starbucks every weekday, so they know my face. Is it a coincidence that I received so many free drinks? I don't think so. I think I have Starbucks magic.
