have you ever faced with this situation? You suggest people to do something but they reject it! after a while the other people suggest the same thing and they accept! can you tell me any expression or idiom that can be used in this situation?
It might not be exactly what you look for, but this might fit:
Some people have double standards.
double standard (noun) = a rule or standard of good behaviour that, unfairly, some people are expected to follow or achieve but other people are not:
- The governor is being accused of (having) double standards in being tough on law and order yet allowing his own cabinet members to escape prosecution for fraud.
