Nearly all hotels I've stayed in there is a single faucet, which blends hot into cold. I recently stayed in one that did the
opposite, I almost got scalded when I turned the shower on.
[Since I have stayed in that hotel many times in the past, I believe a "glitch" occured when they connected the plumbing for
that room.]
In some places, one little thing can end up switched to make cold-into-hot the mixing standard even after the plumbers had properly set it to be "hot-into-cold". It could be a fault that didn't show up when they connected the plumbing and tested it.
