While things will happen, it should always be marked fragile and eggs. The large orange labels catch the eyes better than just writing. If you forget, then when you take them to the counter request they be stamped fragile. It is also good to let the clerk know there are eggs and request they be placed on top of the dispatch. Since it was not marked fragile, it would be stacked with all the others. A heavier box would crush it as the photo shows. The fragile packages are placed on top when transferred. One trick that sometimes helps is to put some stiff cardboard on edge inside to help support any weight. Packing should be put underneath on top and sides. Newspaper packs and will not protect like bubble wrap and peanuts.
