The landlord proposed the 2000 British pounds excavation fee for a simple reason: he didn't believe that anything could be dug up from his property this time, so he hoped to get a visible reward in advance.
After all, in the United Kingdom, treasure hunting is a popular activity. The landlord had experienced several similar treasure hunting requests before and agreed to share the dug-up wealth, but nothing was found.
As a result, the landlord not only failed to make a penny, but also had to spend a lot of energy filling the dug-up soil back in later.
Because of the previous failures, the landlord simply asked for cash this time when he encountered this kind of event again, so as not to end up empty-handed like before.
"How much would it cost to excavate the empty plot behind this building alone?" Leonard Ethan asked. "Compared to the empty plot behind the building, your building is too new."
