It was a small food spot with two single person bathrooms.
They probably just removed the gendered signs and put up “funny” neutral ones.
Not the first time I’ve seen this done, but the first time I’ve seen an alien sign. Got a chuckle out of me and I snapped a pic to share.
Might be a difference in perspective.
I’m in a blue state and this particular neighborhood is mostly genderless when appropriate.
After two dozen simple “bathroom” signs this was nice.
