Why does the shopkeeper of the post station prompt that there is an unpaid bill in the post station to suspend cash withdrawal?

there are two reasons. They are:

11. The cashier at the post office prompts that the post office has unpaid bills to suspend cash withdrawal, because unpaid bills, such as utilities and property fees, will lead to the suspension of cash withdrawal.

12. Due to irregularities, such as illegal activities and illegal fees, these irregularities will also lead to the suspension of cash withdrawal.
