Despite what others are saying, not smarter than a bird, though--my parents' house had a lot of very large windows, and several birds a year would slam into those things, as often as not killing themselves in the process. Good thing birds can't hire lawyers.
No because eveyone knows of windows. The glass doors are not a common life danger.
I don't know about where you live, but I've seen dozens if not hundreds of glass doors in public places that are not Apple Stores. Sometimes a thin metal frame with glass in the middle, sometimes the whole door--very common. Heck, where I work has an 8-foot-wide floor-to-ceiling glass window right beside the front door.
At this point large glass surfaces are a standard fixture in any urban area. If you're 83 years old and haven't learned to tell the difference between open air and a clean glass door, you really shouldn't be shopping downtown at all. And/or, you accept the possibility of tripping on a curb and breaking your arm, running into a parking meter because you were distracted by somebody honking, or running into a door. Just like everybody else does, regardless of age.
And even with what medical care in the US costs, $75K for a broken nose is ridiculous. A million dollars on top of it is just unabashed greed. I'd almost--though not really--give her $2K or whatever it actually cost for the doctor to patch up her nose.
Here's a thought--what if, when suing for punitive damages, you (and, even more importantly, your lawyer) weren't allowed to keep any of it. That is, she could sue for the actual cost of the medical procedure, plus a million dollars that would go into some government fund or something, such that it would punish (hence punitive) the company but not enrich the sue-er... or their lawyer. I imagine that would substantially reduce the number of frivolous lawsuits in the US.
