use Illuminate\Http\Request;
use SonLeu\Barrier\HasBarrier;
use SonLeu\Barrier\Exceptions\BarrierNotPassedException;

class FooController extends Controller 
{
    use HasBarrier;

    public function bar(Request $request)
    {
        try {
            $this->barrier([
                new CheckIfTuesdayBarrier(),
                new CheckVirginityBarrier(auth()->user()),
            ]);
        } catch (BarrierNotPassedException $e) {
            return back()->with('error', $e->getMessage());
        }

        //TODO: your logic
    }
}
