Hello BP,

When you do someone a favour, it creates an obligation towards you on that other person’s part.

When (later) you need a favour from that person, you may feel that they should “repay” the earlier favour. You can then say that you’re “calling in” your favour.

People tend not to use the phrase within the hearing of the person who is to “repay” the favour: the relationship between the two favours is left implicit.

Best wishes,

MrP
