I prefer ketchup on my Arby's roast beef, and there's no end to the grief I get over this. I don't dislike Arby's sauce, I just don't think it adds quite the flavor I want.
Oh, and the horseradish that was near the hotdogs, that was also where the refrigerated pickles were, too. So I think they just didn't have the pink one. My mom tried to suggest that I get some beets and follow some recipe... I have 4 kids under 7, not happening. White horseradish will do.
My assumption with turning the bread packaging inside out and washing it was that it wasn't necessarily being used right away, and was maybe being used multiple times, so eventually any bread crumbs on the inside of the bag would get moldy and you'd need to wash it.
Personally, we do wash Ziplock bags (my husband insists), but I usually just toss the little sandwich bags that just have the flip over. And I never wash bags that held raw meat or anything that went yucky. I do turn the good bags inside out to wash them, though, so I can make sure to get all the way into the corners, etc.
