A guess posted at a gate is usually a sign or a notice that is put up to inform or alert people about something. This can be anything, from the opening hours of a store to a warning about a dangerous animal in the area. The phrase guess posted at a gate implies that the information provided may not be completely accurate or reliable, and that people should use their own judgment when interpreting it.
For example, if a sign says Beware of Dog but there is no dog in sight, people may guess that the sign is outdated or incorrect. Similarly, if a sign says Closed for Renovations but there is no sign of construction activity, people may guess that the business has actually gone out of business. In both cases, the guess posted at the gate may not be entirely accurate, and people should proceed with caution.
Overall, a guess posted at a gate can be a helpful tool for conveying information, but it should not be relied upon as the sole source of truth. People should use their own common sense and observations to determine what is really going on.
