갖다 쓰다 — fetch it and use it, very often something that isn't yours — accounts for five of these lines: 필요하면 태하 돈 갖다 쓰고 (use Taeha's money if you need it), 배우를 이렇게 갖다 쓰면 안 되는 거예요 (you can't just use an actor like this). 뒀다 쓰다 is leaving something a while and then using it. The phrase can sound careless about whose the thing is, which is exactly the complaint in two of the lines.
