We have two sign-in sheets at the front desk. These are for us, the staff, to sign in & out; not for people visiting our office. There are two sign-in sheets because the number of workers in our office spans two pages, A through M on the first page, N through Z on the second.
Because I'm almost always the first person to arrive at the office each morning, when I get in I take yesterday's two sign-in sheets off their respective clipboards, put them on the "old sheet" stack under the counter, get two new sheets from the "new sheet" stack, write today's day & date at the top of each page, clip them to their clipboards, then check off my name on the second page as being "Present!".
This morning I got in and saw someone had beaten me into the office, and they'd put a new sign-in sheet on the first clipboard. That is they'd taken the first sheet, the A-M sheet, from the new sheet stack, but only the A-M sheet because their name is on that first sheet, so obviously they don't need the second sheet. Duh! Then they put that new A-M sheet on top of Friday's sheet, dated it, checked off their name, then toddled off to their desk.
I looked at the sign-in sheets for a few seconds, almost unable to believe that someone would take out and date only that first sheet because that was all they needed. Almost.
I sighed, and reminded myself that coworkers can be friendly but that doesn't make them friends. Then I unclipped Friday's sheets, put them under the counter on the "old sheet" stack, took the page of N-Z names off the new sheet stack, clipped it to the clipboard, wrote today's day & date on it, checked off my name...and then...
I took another sheet from the new sheet stack, being the first page of A-M names.
And I wrote today's day & date on top of that page.
And I replaced the sheet my coworker had used to check off her name with this new sheet, and I put "her" sheet on the "old sheet" stack.
And no, I didn't check off her name on my new A-M sheet. Bwah hah ha!
No, she won't get into trouble for not checking in or anything like that, but I gained a certain amount of perverse pleasure plus the satisfaction in redoing the entire "job" and not just "finishing what she'd started".
With that I went to the breakroom to get a cup of coffee and discovered she'd already been in there too, and that while the kettle was on to boil so she could make herself a cup of tea, Friday's 3-day old coffee was still sitting in the pot. Lovely.
