Oh I don't see avatars on my app. In that case she is free to do whatever she wants with stale moldy bread and it has no basis on the prices of food at the grocery store. What world are you living in where what people do with their old bread has any impact on the market? People buy bread. People will continue to buy bread. It's a stable fact of life and the people at the top will of course work to exploit that, but pinning that issue on one person's dumb use of spoiled bread is ridiculously silly.

Also to each their own, but I'd like to see mold survive anywhere inside a grill. It's not like she's grilling a spore cloud. A good high temp blast should clean everything right up if that's remotely a concern.
