Help with identification of token

Got this token. Look`s like French. If somebody know anything about it - tell me please.

Thank`s.

 I think (but not sure) it may be from a commune at Trappes in France ...

 Welcome to the forum.  

So. It`s a token of 35th anniversary of "public service" in Romainville. The French commune in the eastern suburbs of Paris, France.

I understood correctly?

And what does it mean public service?

Thank`s. I`m glad to join.

 That is correct, to what those pages said.
As Numista is originally a French site, maybe you can ask on the French forum ...

 as they would have a lot more knowledge about it on there.
