For who? The Church, a non-profit does not have tax write offs. The business of course wrote the refund off because you do not pay taxes on losses. I have no idea what you are asking.
This entire story is absurd. She was wrong and she did talk crap about the church online. I would fire her for that myself. The food comes boxed and only needs bagging coming from the backend. She did not spend her shift (8 Hours) as she claims making this order. She put it in bags and put it in a car.
I don't have to tip and only do so when service is excellent, or I can see the waiter working hard.
Say she offered bad service and didn't deserve a tip? Does that mean that now everyone gets to drag the Church through the mud? What if she was super rude? Made them wait to be helped? I guess that would not have even mattered, because no waited to even hear the churches side before jumping to conclusions that the church was bad.
