But which Tier were they in?

Mandatory evacuations cost people money. Very often the expense exceeds people's disposable income. If the government is going to force people to spend money they don't have, it should plan to compensate them when they return. If the government is going to arbitrarily force some people to stay away longer than necessary, then we might be talking about punitive damages.

Of course, according to the Mayor, none of this would be a problem if we all worked in the hyper-lucrative food prep industry.
