Have you ever worked in a shop? I have had jobs like that where I thought I would die of boredom from the acres of space with no customers. But it can be fun if/when you develop a good rapport with customer, you have a bit of a laugh and a chats, then you find them just what they want and they buy it.
NB the mark up (and hence the commission) in furniture shops is pretty big. But the wages are low and staff are under pressure to meet their sales targets.
