Creamer? DEAR GHOD! Vade retro rotten white powder in a packet. I went on a residential course years (about 19 years actually) ago and found myself provided with this vile creamer muck. So I went out and bought a pint bottle of milk. Now as the older ones amongst us will know, if you haven't got a fridge in the room (and Marconi College didn't) milk will stay cool and fresh if stood in water half way up the bottle. A damp (clean yech) handkerchief draped over the bottle wicks up the water and cools by evaporation.
I would come back after classes to find the water drained, the handkerchief neatly folded and dry, and the bottle of rancid milk stinking on the draining board.
That's why I got into drinking coffee black (sorry, without creamer). I drink most things without creamer.
