Given that I like their food and they have locations near me, I am a Panera frequent guest. I hate their loyalty program, however. No set items, just random bonuses on your card. Think of the gerbil pushing the lever to get goodies.
Well, I've been pushing the lever frequently and nothing has come out. One of the employees mentioned to me that new cards tend to get more goodies than existing cards, so I signed up for a new one. I'll report back if I get anything good.
