Most DMs will roll a second time for 1's and 20's to see just how epic your fail or success was. This could be two tens for 01-00.
If the enemy steps on ball bearing and rolls a one...and then a second 01 is rolled...well than they might just break their neck and be laying there paralyzed and gurgling.
That's table top thinking...fuel for thought only.
No, "most DMs" do not. Perhaps most you've played with but that is 100% homebrew.
