I'm so relieved to report back on what the situation here was.I popped in to a client's office before to pick up a box of something he wants me to start working on first thing tomorrow. It's night-time where I am, and I have a key and permission to go in at anytime.
I was confused and surprised to see someone sleeping in the reception area (in a sleeping bag - I went in very late and woke them up when I flicked all the lights on)!
My client has two offices on this floor; the rest of the floor is leased by another business altogether (including reception). Given that's where they were sleeping, I'm going to assume that they are somehow related to that business.
It's very odd and concerning ... nobody should be sleeping in offices! I've never seen this person before, although I only pop in occasionally so don't know everyone who works there, but now I can't stop thinking about it. I texted my client to let him know because I thought someone should be aware; in his usual style, he just texted back, "thanks."
They weren't the cleaners, as - weirdly - they've never had any ... people just clean up after themselves and occasionally once in a blue moon someone will get the vacuum cleaner out and give the floors a going-over.
So, so strange.
I called into the same office this morning to drop some things off, and the person I saw sleeping in the reception area the other night was there with someone else; they were dressed in overalls and wearing hardhats, while looking at some plans they'd pinned to the wall. I said "Hi," and they smiled and said "Hi" back.
As I was about to leave, the person I saw sleeping there the other night came in and introduce themselves and explained that they're working on some infrastructure project that has to be monitored closely in case any alarms are triggered, so that's why they stayed over (obviously my client had mentioned to them that I'd asked why they were doing that).
I'm so relieved it was all above board; it is concerning from a health and safety point of view too - I'd hate to think what would happen if a fire broke out and nobody knew there was someone in there.
