Steps:
When eating Omlette Sandwish +1 or Egg Sandwish +1, the food buff duration is only 30 minutes, which for a +1 food seems like an error.

Red curry bun +1 food duration is also only 30 minutes and has been for many years. So this may very well be intended feature for a "snack" type food like sandwich that is not generally considered a full meal.
