hobnob

Momoが住む町にthe Timesaving Bankのthe men in greyが出没し、人々に時間の節約を勧めています。 床屋のMr Figaroのところにもthe man in greyがやってきました。
Work faster, for instance, and stick to essentials. Spend only fifteen minutes on each customer, instead of the usual half-hour, and avoid time-wasting conversations. Reduce the hour you spend with your mother by half. Better still, put her in a nice, cheap old folks' home, where someone else can look after her -- that'll save you a whole hour a day. Get rid of that useless budgerigar. See Miss Daria once every two weeks, if at all. Give up your fifteen-minutes review of the day's events. Above all, don't squander so much of your precious time on singing, reading and hobnobbing with your so-called friends. Incidentally, I'd also advise you to hang a really accurate clock on the wall so you can time your apprentice to the nearest minute.
