What is the meaning of ずれる on this sign?


I found the below sign in a [tweet about the new ordering system at
Saizeriya](https://twitter.com/nokonk0/status/1673167450446389253). What
puzzled me is the text on the sign at the bottom-left:

> 右側のイスにずれて、順番にお待ち下さい。  
>  Please wait in line by ???ing at the chair to the right.

Ignoring the poor English translation, what is the intended meaning of ずれる?
[Looking it up in a monolingual
dictionary](https://dictionary.goo.ne.jp/word/%E3%81%9A%E3%82%8C%E3%82%8B/), I
only see the meanings I know, which refer to being displaced from an intended
position (with nuances of being wrongly in that new position).

What, then, does the sign mean by イスにずれて?

The sign is asking you to "slide" or move along to the chair to your right as
you move forward in the line.
