-(으)시-
-(eu)si-
Not bowing down — lifting them up
The picture Sliding a small platform under someone inside your sentence, so their seat sits one level higher. -시- is a platform under the subject inside the sentence; -습니다 is the outfit the whole sentence wears. Who gets raised and where you are speaking are two separate layers.
Where the picture shows up in -(으)시-
-

son-nim, mwo cha-jeu-se-yo
What are you looking for?
Across the counter, only the floor the customer stands on is one step higher.

-
swapping in a whole different word
할머니는 안방에 계세요.
hal-meo-ni-neun an-bang-e gye-se-yo
Grandma is in the back room.
Instead of adding a platform, swapping the word itself for a taller one.
있다 doesn't take the platform — it becomes 계시다 outright.
All of it in one picture
-시- is one platform, slipped into the sentence. Push it under the chair of the person in front of you and it becomes an invitation; leave it under an empty spot and someone who already walked out still rides higher; set it under your mother's feet and a family elder rises; set it across the counter and the customer does. Where a platform is not enough, the word itself is swapped for a taller one. In all five, nothing shows you crouching — only the other person's seat coming up a level.
