If the Tower Controller ever tells you to expedite roll out speed to clear the runway, and you can tell that it is slippery, just say "NEGATIVE TOWER", and take your time turning off of the runway because there is a high probability that away from the runway(s), it is almost always worse braking action than on the runways. The controllers sequence traffic, but WE receive all blame if an airplane gets stuck or damaged-unless tiny bits of the huge paragraph of airport NOTAMS and other info are proven to be in error.
Sometimes these high-speeds and taxiways are much worse (not even treated with chemicals and sand!), and it is possible that tower will tell you about this, even after calling it a "PIREP", due to very high workloads. , numerous blocked radio transmissions
Of course this only happens in the US, so it can't be any real problem out there in the real world.
