Lambert shared his interests and knowledge of sports, dogs and animal husbandry with London's middle and upper classes, and it soon became highly fashionable to visit him, or become his friend. Many called repeatedly; one banker made 20 visits, paying the admission fee on each occasion. During this period of English history no real stigma was attached to obesity, and Lambert was generally considered a wonder to be marvelled at, rather than a freak to be gawped or sneered at. His business venture was immediately successful, drawing around 400 paying visitors per day. His home was described as having the air of a fashionable resort, rather than that of an exhibition, and he was pleased to find that his customers generally treated him with courtesy, and not simply as a spectacle. He insisted on maintaining amongst his visitors an atmosphere of civility and all men entering his rooms were obliged to remove their hats. One visitor refused to remove his "even if the King were present" but Lambert replied that "Then by G——, Sir, you must instantly quit this room, as I do not consider it a mark of respect due to myself, but to the ladies and gentlemen who honor me with their company."
