What's the need of allowing user join morethan 1 game rooms?

[Vishwas]

Is their any practical scenario where a user is allowed to join more than one game rooms ? ( This is with respect to the parameter in function sfs.joinRoom() , where one can set , if user wants to leave the previous room or not ).

I wonder, why would anyone allow a user to stay in previous room ? Only one advantage can be retaining the information of user in previous room. Otherwise, is it really feasible, to be present in more than 1 game rooms simultaneously and playing a game in each of them ?

One of the practical scenarios could be where:

User creates a game room, joins it and waits for other players. While the user is waiting for other players, he joins the lobby room, whilst not leaving the game room, and look if there is anyone in the lobby and invites them if so. Once done, the room creator then can return to the game room and starts the game.

On a side note, joining multiple rooms at the same time can result in needing more bandwidth. So, avoid having users in multiple rooms where possible.
