To reiterate how bad public transit is, even in populated areas: I’m also in DFW. This is my daily commute…
It’s ~9.6km. Note that the bus/train option is entirely greyed out, because there is no public transit which runs from my house to my job. If I were to walk, the only option would be on the side of a highway. I would have cars passing me at ~70 MPH without even a curb for protection.
To walk to the nearest grocery store, it’s ~4km, with a large part of it along the shoulder of that same highway. Same with a major chain.
Nearest bus stop is ~6.9km, but that only takes me in a direction I wouldn’t need to go; There are no local bus or train stops that land me near where I work or live.
Bathroom attendants are there to discourage drug use and bathroom sex. That’s literally their primary purpose. The fact that they have towels and mints is secondary to the fact that they’re just a walking overdose deterrent.
That’s why they’re commonly seen in clubs and bars where people would be inclined to do drugs or have bathroom sex.
