The client had a separate network off the Internet hence physical presence was required to access the contents needed to build/deploy that particular internal site. Machines were loud, even behind the closed door. Naturally the place was completely filled with coffee beans of all kinds in all stages of processing, and just after an afternoon there both my boss and I smelled like coffee - the scent was transferred to his car so it still smelled like coffee the next day I stepped into that car.
What's more unusual is that it was running a rather old Red Hat distro (for its time even; Fedora was already out for nearly two years at that point) and they only gave me the root account. No XFree86, so a 80x25 terminal on a 13" CRT screen, and of course no way to install anything else aside from what's there (Apache/PHP and vi (not vim) for editing). I can't even remember how I got the skeleton project files onto that machine, might have been a 3.5" floppy, I really forgot about that part.
At that time I felt like I was thrown back a few years back, but thinking about this now it would have been a stranger experience today.
