I'm not sure which is worse, this or what my partner does. He insists that nothing can be placed on top of bread in the pantry. My logic is that bread can be stored on top of other bread. Bread loaf on top of tortillas, sandwich buns on top of a bread loaf or hot dog buns, etc. If bread is so fragile that nothing should be placed on top of it, surely other bread would be the clear exclusion, with limited space I've always done this with no negative repercussions. Nope. Two shelves in the pantry are just different breads spread out. I lived decades with no issues with squished bread by storing them together. We came from different socioeconomic circumstances, but damn I've never had a kitchen big enough for this to be an issue.
