Did it show up as a public charging station on Plugshare? I saw that you could write a review about it. I think that information would be helpful for other people to know.
The beauty (and problem) with plug share is that anybody can add or edit a public charging station. I've added a couple myself. It's up to the reviewers to provide the details, which is exatly what I did.
It's also possible that the salesperson was missinformed about the charger and that it was indeed a public access charger.
NEMA 5-20 has a vertical "eye" in the top right, NEMA 6-20 has a horizontal "eye".
Ah yes, the 240V socket is "winking" at me.
