I don't know TurkeyLady, so it could well be true that the assumptions made here about her are true and she intended to double dip and nefariously stole the turkey dinner.
But it COULD also be true that she was worried things wouldn't work out. Perhaps the deli told her the turkey had to be claimed by Thursday afternoon, so she wrote it on the coupon. And then, having been to the deli, she was worried about so many employees. What if they didn't honor the coupon? So she checked up several times, because she wanted to make sure it went smoothly. Well, it didn't. Nobody showed up to claim the turkey at all. Since it wasn't a church member who won, she had no contact details available. So she ran and picked up the turkey dinner and donated it to a women's shelter or even the church's own mission. She would still be in the wrong, IMO, unless she ran this final choice by the church and they agreed to the plan. But she doesn't necessarily have to be a greedy woman perched on her chair ready to swoop down and eat someone else's dinner. It could just be a moment of bad judgement.
Either way, the church needs to be aware of how this played out. If the dinner was donated gladly and fetched a price near what they hoped, they are likely to repeat it next year, completely oblivious to how poorly it turned out behind the scenes this year!
