Man, that hurts to read because I did the exact same thing for way too long with a foam block. Found out the hard way when a customer pointed out a wavy spot in the sun that I thought was perfect.

The leather sagging thing is really about the core, cheap ones use bonded leather that's basically cardboard with a coating. Webbing's also way easier to clean if you work outdoors or sweat a lot, a quick hose-down and it's good.

Guess that graphene pad was more of a fancy space heater than a cooling solution. At least your drawer had the real hero waiting to save the day.

Wait, you actually made it three days on hostel WiFi in Lisbon? I would've lost my mind by hour two. I tried that once in Porto and ended up standing outside a McDonald's at midnight just to load a bus schedule. The free WiFi thing is such a trap, it's like the universe punishes you for being cheap. Ten euros for a SIM is basically the price of one tourist trap pastel de nata and a coffee, so that's a no brainer. I'm honestly impressed you didn't chuck your phone into the Tagus on day two.

Ever had a buddy swear up and down a charger was dead, only to find out it was their own port the whole time? My friend Mike drove 40 minutes to a repair shop with a "broken" tablet, and the guy there just looked at the charging hole with a flashlight, wiggled a paperclip in it, and it worked fine. Sometimes the problem is hiding right in front of you, and the cheap fix is just a little patience and a closer look.
