Nitpick, it’s JCPenney.
It’s also not “Penny”.
California Real ID license states “Driver License” (maybe a license for drivers?)
I googled to see what Utah has because mine expired years ago. It looks like driver license.
Interestingly, I found a story from the local news about progress on testing a secure digital license and the head of the division says “driver’s license.”
I know we did this recently in the context of some other linguistic pet peeves marathon thread. I’m not now remembering a magic word I can use to find my post there to find the thread for us to re-enjoy.
Anyhow, back in the late 19th & early 20th century, the vast majority of retail stores were Mom & Pop one-offs. Very often named for the owner / founder / proprietor / only employee. “Smith’s Dry Goods” being an achetypical example. Often shortened by customers as in “I’m going to go buy stuff at Smith’s” Which makes sense.
Where it falls apart is for stuff named for a corporation, not a person. “I’m going to go buy stuff at 7-11’s” is a nonsense.
Sometimes it is.
Which of course, has nothing to do with what we’re talking about.
Which has in the past used “Penneys”.
Something that I often see with an apostrophe is how to correctly reference a decade in writing, as in 1960s or 1960’s. I wrote for a newspaper for a time, and was told that it was properly 1960s, without an apostrophe, and that’s how I have written it ever since. Yet from what I gather, either is now acceptable, which makes no sense to me. It’s a plural, not a possessive.
One that I particularly like is: a pair of Levi’s. I like it because, while it looks (and feels) wrong, it’s correct.

Nobody has the right to prevent you from sounding like an ignorant hick. 
Here in St. Louis, just to be contrary. when the Schnuck and Dierberg families grew their local grocery stores to become the dominant supermarkets in the area, they became Schnucks and Dierbergs - no apostrophe.
Anyhoo, i tend to think that kroger owns a grocery store, hence it kroger’s grocery store.
Lyme’s disease is actually Lyme disease.
I work for Winco and I’m constantly having to have people rewrite checks that they’ve made out to “Winco’s”, as if the company was founded by a guy named Steve Winco or something.
I just shake my head when I drive by a house where the name on the mailbox or on the house says The Smith’s or The Clinton’s or The Whatever’s.
And in Kansas it’s Driver’s License.
I have no issue with it, except perhaps in formal correspondence.
How I write on a MB or FB has no comparison to how I write a Business Compliance manual, for example. That turns into legalese and boilerplate.
the Smith’s house. the house belonging to the Smith family. as opposed to the plural members of that that family the Smiths.
Not far from us is “Two Cousin’s Beauty Supply.” I have to stare as I drive past, as at a bad accident.
ok i seem to be a minority on this. If two cousins own a beauty supply store why isn’t it Two Cousin’s Beauty Supply.
Doubtful if The Smith’s on the mailbox refers to the Smith’s mailbox, however.
Also, Home of the Smith’s is not uncommon, either.
