You can use View Composers:
View::composer(['store.index', 'products.*'], function($view)
{
$view->with('client_to_show', $client_to_show);
});
You can put that in your routes file, filters file or, like, me, create a app/composers.php
and load by adding
require app_path().'/composers.php';
To your app/start/global.php
file.
View Share is another option:
View::share('client_to_show', $client_to_show);
