Вместо недели уже прошел месяц, как всегда. Обычно, меня это не парит. Могу понять и проблемы, и другие заказы.
Но в этот раз Руслан еще и пропадает постоянно, прогнозировать результат невозможно.
Принимаю работу, как есть, чтобы не портить новогодние праздники арбитражем.
Но в будущем к Руслану обращаться больше не буду
