What interesting and unpopular occupations have you heard of?

Bicycle couriers, also known as bicycle messengers, provide valuable services to the city. Bicycle messengers play an important role when road traffic is very inconvenient. Bicycle messengers will not be stumped by traffic jams. They are usually faster, safer and more efficient than cars in cities to transport what employers need. Although the arrival of the digital age no longer requires bicycle messengers to deliver newspapers or some letters, cyclists are still favored by all walks of life, such as food and fashion industries.
