From my experience/perspective, Buc-ee's got cleanest restrooms, Patels got the dirtiest.
Well, I'm impressed with Buc-ees restrooms, but I've used restrooms from the caribbean to Southeast Asia and India, from Mexico to Chicago; I've peed in the East, I've peed in the West, I've peed all over this world but the worst public restroom I ever went in was at a little gas station somewhere in west Louisiana along the Tx/La border in the early 60s. There were dead and dying mammals, birds and insects (hundreds of spiders, crickets and ants, along with BIG spider webs) in it and that doesn't even take into account the filth from humans in there. The women's facility must have been just as bad as my mother complained mightily about it when she got back in the car.
Heck, I spent a year in a place where you pooped in a cut off 55 gal drum, alongside other hhairy assed gentlmen, and not unusual to have some old woman come along, open a wooden flap and jerk the drum out mid poop and replace it with a fresh one every few days. Then, some unfortunate young low ranking Marine had the task of adding 5 gals of diesel or JP5 to the drum, setting it afire with a bit of c-4 and keeping the whole belching black smoke mess stirred with a long stick of pipe so most of it would burn up. The smell was unmistakable...and not one you ever forget.
I do like Buc-ees a great deal but as they expand I do have to wonder if we will see the same undesirable effects we saw when Walmart took over the retail/grocery world over a period of a few decades.
I have to wonder if what we see today is what old Sam Walton would have wanted...
I find it ironic, that truckers complain they aren't welcome at Buc-ees fuel islands, when for many years, they complained about the 4 wheel vehicles causing them problems at truck stops. Now they can eventually have all their truck stops back to themselves but they're still unhappy.
