Largely as above; volumes, light-switches, plug-sockets turned on when they have nothing plugged into them, also had the radio timer one.
Another I have is counting things. Anything countable* I used to count. About a year ago at work I was in the kitchen when someone came in and started filling the coffee machine with scoops of coffee. They then said 'oh I've lost count' and I was just like 'yeah you put 7 in…'
I just walked out as their eyes followed me, looking bemused.
*Not as bad as it used to be now, thankfully.
