History trivia: you might think that sending a bunch of deliveries is a modern thing, made possible by the telephone. But no, if you were sufficiently dedicated you could do it back when you had to send letters to order stuff.
In 1809 this [1] happened in London:
> On 27 November, at five o'clock in the morning, a sweep arrived to sweep the chimneys of Mrs Tottenham's house. The maid who answered the door informed him that no sweep had been requested, and that his services were not required. A few moments later another sweep presented himself, then another, and another; twelve in all. After the last of the sweeps had been sent away, a fleet of carts carrying large deliveries of coal began to arrive, followed by a series of cakemakers delivering large wedding cakes, then doctors, lawyers, vicars and priests summoned to minister to someone in the house they had been told was dying. Fishmongers, shoemakers and over a dozen pianos were among the next to appear, along with "six stout men bearing an organ". Dignitaries, including the Governor of the Bank of England, the Duke of York, the Archbishop of Canterbury and the Lord Mayor of London, also arrived. The narrow streets soon became severely congested with tradesmen and onlookers. Deliveries and visits continued until the early evening, bringing a large part of London to a standstill.
The person behind that wrote thousands of letters to set that up.
