That's what I found to be such a distraction to the series. It's badly written shonen after the first chapter. Terribly written.

All the tonal mistakes it make, High School of the Dead never did, goofy ecchi aside.

Cemetary visits and using the home altar is not the same as showing a decent depiction of grief. The characters are usually long over it, and it comes off as household routine.

This is just flippant disregard for the lives of others, which sharply undermines the main point of the first episode.
