Things that should be hot

Drinking luke warm coffee is ok only when you've no choice or if you've been nursing it for the last couple of hours whilst reading a book/ magazine, surfing the net or when out shopping. Else, for me it should be hot. Same applies for "hot" chocolate. Tea is a different story.
A hot day is a good day for the beach. But remember the hat and sunblock.
Hot chips (fries), need to be hot, they just don't taste the same when they've been sitting there for half an hour left to cool and you can see the oil blots on the paper bag.
Onsen and saunas - I can't officially say I have sat in a sauna, but I'd imagine they'd need to be hot'n steamy. Onsens must be hot for obvious reasons. It needs to feel like your skin is being scorched (cleaned?).

Enjoy your coffee!
