Yep. An indication that the workers are probably illegal aliens.
Right now....whether in Amsterdam, Frankfurt or Paris...hired-help for cafes, bars and resturants is getting to be impossible to find. So they are all expanding efforts to hire non-natives. That means if you were in Budapest last year as a bar-waitress...you probably were approached to take up a job in another country. That means your old job in Budapest lays there...empty, unless they entice someone from a lesser country (like Bulgaria or Romania).
Everyone, in this after-Covid era....is stealing each other’s employees.
