1) You just found something that is quite complicated for foreign speakers to learn in German language. If we are speaking about a specific address or a city German speakers are using "in".


Wir treffen uns in Frankfurt.

Wir treffen uns in der Frankfurter Straße.

The Straße in "Frankfurter Straße" does not mean the street itself as an object. You don't stay directly on the street. First example should be clear: You are meeting somewhere in the city of Frankfurt.

At the beginning "meeting in a street" may sound weird, but it's the way we say it. When you say "auf der Straße" you usually mean outside at the street or on the walkway.

Same thing with the "Markt":

  1. Wir treffen uns auf dem Markt

This could mean a) on the marketplace outside, or b) if there is a specific market like "Wochenmarkt" which can also take place inside a hall, it could mean that you are meeting in the hall, but at the market.

  1. Wir treffen uns in dem Markt

This usually means that you are meeting at a supermarket. It's in a closed building and you are meeting into that building.

2) The difference is pretty easy: The first one is correct, the second one isn't. You are using the wrong Kasus. It has to be "in dem Geschäft".

  • +1.In the last case the wrong way could be used sloppily when leaving out a trailing 'gegangen': wo ist denn Julia? - Die ist kurz in das Geschäft. Commented Sep 28, 2023 at 3:41

About your second question, "Justyna ist in dem Geschäft." is correct. Because whenever you want to use the "in" preposition before a specific place, and your sentence does not include any movements associated with the place, it has to be written in Dativ form.
