I live in Spain and do domestic flights quite a lot (although, high-speed rail is looking better for me every day… 2h30 from city center to city center vs a 1h20 flight plus the train from and to the city, rail is sometimes better), and I always follow the same procedure: take off my watch, empty my pockets, remove my belt, get the tablet/laptop out and put everything in a tray with my backpack on top of it. I've been asked several times to remove my shoes when those shoes were 'high' shoes, ie. covering a bit over the ankle. Now every time I fly I make sure to have the right shoes, and start removing stuff before arriving at the checkpoint. It does't take long to get past security (I've done under 5 minutes), but still I have to get half-naked and often checked. And it's annoying. HSR (and leaving the VIP lounge, already included in the ticket which has a very reasonable price, ten minutes before the train leaves) is so much better. And just walking past security without having to get half-naked, that too (get your bag through the X-Ray to see if you're carrying something huge and dangerous and that's it).
