For quite some years I supplemented my regular income by doing tax returns for about 15 clients and although much of the work could be accomplished with TurboTax, there were always returns which required more esoteric forms and instructions. In order to acquire these I would walk over to the federal building in downtown Pittsburgh and acquire my paperwork. On a day immediately following 911 I was stopped at the front door of The Federal Building my reason for desiring ingress was considered too inconsequential and I was denied access. The tax return eventually got done but my client was astounded by the difficulty involved in reporting and paying his taxes.
For Most of those years I was known to my clients and colleagues as just Bill. But that's another story.
