or email to/from/cc in ios mail, where only the person's name is shown. clicking on the name displays a contact card. for people with multiple addresses, there's no way to tell which address is being used.
Yeah this is incredibly stupid. If you have a contact with more than one number trying to call you, the only way to know which number they called u from is the little accent to indicate recently used in their contact card. God knows what happens if they tried to call you from more than one number ...
