I like the idea of these new rechargeable cards. I'm in and out and I'm not charged a POS charge everytime I use it. I read an article where the employees were concerned that this would affect their tips. I'm a very generous tipper to that attentive waiter/waitress at a restaurant. I'm struggling a bit with why these baristas feel so worthy of a tip. Do you tip at Starbuck's? How much? I feel my server at Carl's Jr. much more deserving.
