This often proves difficult and can take a long time so I will ring a bell so that everyone knows it's time to eat! Hopefully this will speed things up a bit.
事实证明这很困难并可能需要很长时间,所以我会提醒每个人,是时候吃东西了!希望能加快速度。

If there were an omniscient central planner, she could simply ring up the sort-of hungry guy who decides he may as well drive to get that burrito and tell him to wait a bit.
