Cách sử dụng
The expression "do somebody no favours" is used to indicate that something someone does may not actually be helpful or beneficial to the person they are doing it for. It can be used in various situations when someone does something that may seem like a good thing for someone, but it actually ends up causing more harm than good. For example, if someone tries to protect their friend by not telling them the truth about a particular situation, they may be "doing them no favours" as their friend may end up getting hurt in the long run.
