What's the difference between i.e. and e.g.?
To collect what is owed to one, esp tit-for-tat political or other favors: I have no chits to call in from politicians/ You're calling in your chits, Ivar/ For the Titian show, Michel Laclotte, soon to retire as director of the Louvre, has called in all his markers at once
[1980s+; fr chit, ''notation of something owed, IOU,'' attested fr the 1770s; the source is Hindi chitti;a marker is also a notation of debt, esp in gambling]
