We always had to have a paper towel in our pocket for spills.
Fifteen or more years ago, on a cold, sleeting night, I was exiting my local Safeway and stepped off the curb in front of the store into the parking lot. I was walking normally, not in ice-storm-defense-mode, and I stepped onto a patch of black ice and went flying. I was gratified that long dormant football skills kicked in, and I rolled through what much have looked to bystanders as a quite spectacular head over heels tumble.
Were I a democrat, I suppose I could have stayed down, clutching my back, head, and knee, and groaning softly. I would probably be retired by now. As it was, I rolled through the fall, embarrassed because I had been careless, and popped up with no harm done. Not even a bruise. There were, btw, half a dozen Safeway employees on the spot in a flash; besides being a friendly crew at that particular store, they had probably sat through the same safety lecture you had.
Is Safeway liable for having black ice on their parking lot in the middle of an ice storm? The conditions were clearly sleety. I should have been paying better attention. Where does a company's liability end? I do not think trial lawyers should draw these lines.
