[contingencies]

Hotel room interface problems I have known and loved: lights with no switch at all (instead you need to origami your hand inside the shade or twist some rotary knob integrated in to the peak of the lampshade), central control panels with modal groupings that don't match real world use ("night mode", "evening mode", "reading mode", "interior designer mode", "electrical band-aid mode", etc.), devices (TVs, kettles, phones, remotes, ACs, AC controllers, fridges) with perma-idle lights, inaccessible power points so you can't just de-power them, dodgy keycard inserts, keycard inserts that take paper, blinds that have remote control only so you can't move them naturally, AC that doesn't work (classic is 'central control' AC with no actual in-room preference - becoming extremely popular in 'mid'-range chain hotels but I've seen this in "5" star places), windows that don't open, towels stashed in irritatingly inaccessible or invisible locations, disfunctionally small bins, minibar-dominates designs, the prestocked minibar-fridge-as-sole-fridge where you actually need the fridge for something else, one could go on...
