After a 4 month absence due to E. Coli situation (I've even been avoiding it in airports where it used to be the clear favorite), I got the freebie and used it tonight (though they were being quite skimpy on the chicken). It's been been ~5.5 hours and so far it seems I am E. Coli free.

Apart from the skimpy chicken it may have been enough to convince me to start going again.
