People say a lot of this stuff is just "five minutes in your lunchbreak", but is there something magical about the 9–5 commuter lunchbreak lifestyle that makes these tasks always actually take the five minutes they should? Because in my experience, a good chunk of what should be quick 2 to 5 minute tasks end up taking way longer.
For example, couple of days ago, I wanted to transfer some money, went on the bank app, took two minutes, sorted. But apparently something about my (innocent) transaction tripped the bank's fraud alerts, which initiated an immediate automated call from the fraud team. Waited on the phone for, I dunno, ten or fifteen minutes for it to connect to a human, at which point the sound went garbled and the call disconnected. Checked the app, transaction suspended. No follow-up call from them, so at the next opportunity (next day I think), found a bank number to ring, waited in a long queue, explained the problem, was transferred, waited in another long queue, then went through a 15 minute identity and past transaction grilling, so the transfer could go ahead. One two-minute job taking at least an hour in total.
Or today, I had to quickly print a blood test form at home before leaving for my appointment, because apparently that's how it is here now. Should take me a couple of minutes max, but various boring tech issues meant it took over twenty minutes.
With any random selection of, say, a dozen "quick" admin jobs, in my experience at least one of them ends up taking way longer than you anticipated.
Also, booking a restaurant counts as life admin in my book (especially if like me you're a coeliac and want to have a reasonable chance of actually being able to eat with everybody else). It's like people see the words "choosing and booking a restaurant" and think only of one individual joyfully selecting what option would delight them personally the most, rather than someone having to consider scheduling and distance from party members and budgets and dietary needs and accessibility.
