Спасибо, - улыбнулся Беккер и повернулся, собираясь уходить. Консьерж бросил внимательный взгляд в его спину, взял конверт со стойки и повернулся к полке с номерными ячейками.

Когда он клал конверт в одну из ячеек, Беккер повернулся, чтобы задать последний вопрос: - Как мне вызвать такси. Консьерж повернул голову.
