my wife and I went, there was a pretty good crowd for about 9 pm, the stalls were mostly full so we just drove straight thru, waiters and waitresses were out at drive thru with trays of floats already prepared.
mine was melted, so no good, but my wife's was good and she is on a diet so gave it to me.
did they make a profit? probably, judging by the cars parked at the drive-in, regardless, the good will generated and widespread press including tv and yahoo finance was priceless.
Now if they can just get sp/moodys off their back, generate some profits, and pay down more of their debt.
Tuesday will be the story at conference call. Usually stock performs one way or the other near the target day.
