[windex]

A lot of companies seem deeply invested in corporate offices and office complexes. It helps them with expense write-offs, depreciation etc. If you suddenly stop using those facilities, it's a dead asset.

In some countries, running employee services like the cafeteria, transport, taxis, facilities management, security etc are usually hived off to family members of the promoter, allowing for invoicing at inflated rates to reduce tax outflow of the main business. If the offices didn't run many found it difficult to hide actual incomes.
