M. Blondin does not regularly pay special attention to his clients. Only in the rarest cases does he "with gracious condescension, greet a guest, accompany him to a privileged table, and exchange with him suitable and apposite remarks".
M. Blondin is "positively fulsome in his attentions" when Poirot comes to his restaurant at the beginning of the novel. Although customers had been told for the past half hour that there were no tables available, for Poirot, a table mysteriously appeared at a favourable position, and M. Blondin conducts him to it. This causes Poirot to remember an incident involving a dead body, a waiter, M. Blondin, and a very lovely lady.
