Stuck in Madrid for three hours longer than planned/ideal. I couldn't make the reservation that needs to go with the interrail pass for the Madrid-Sevilla train except in-person (myself - tried to send agents in advance, no go) at the station. After standing in line at two different renfe ticket offices before being told "not this ticket office" I waited for 30 minutes at the third to be told the last seat on the 5pm train went to the person in line before me. I blame the massiveness of Madrid station. So my only next option was first class on the 1958, which gets me in way past my bed time. Alas. At least first class was only 3eur extra.

And I have discovered that there are free toilets after the baggage security check. The WiFi at Rodilla cafe near platform 15 works, and the nice person at Rodilla filled my water bottle with ice cold water for me.
