The expression "fair's fair" means that something should be done or treated equally and justly. It is used to express the idea that everyone should have a fair chance and should not be favored or discriminated against. This expression is commonly used to remind someone of this principle when they are acting unfairly or in a biased way. For example, if a teacher gives extra credit to some students but not others, someone might say "fair's fair" to remind the teacher that they should treat everyone equally.
