The offer improves when its details remain attractive after the excitement fades.

Excitement is part of nearly every offer, and it is the part that expires first. What remains afterwards is the ordinary shape of the thing: the hours, the terms, the travel, the clause about what happens if circumstances change. A generous headline and the conditions beneath it are two different objects. The conditions are what you will actually live in.

Read the details again on a dull morning rather than in the moment of being asked. Picture a bad month under this arrangement and see whether it still holds. If it does, your enthusiasm was probably right.
