Yes, on average this would slightly affect the result, but I'd be shocked if a non-negligible number of trips to the gas station for most car drivers involved entering the convenience store, particularly to "hit the restroom". Most people spend their lives driving back and forth between two places that have clean and (certainly relatively to a gas station) pleasant restrooms: the only people stopping at a gas station are on long road trips; and while I do a ton of these, I'm still usually not doing it a gas station: most people are probably stopping at whatever their favorite fast food restaurant is and going to the bathroom there, which satisfies their food craving at better cost efficiency than the overpriced even lower quality junk at the gas station and, at least today, doesn't parallelize that well with either filling their gas tank or charging their battery. (And except during small windows of time when only desperate people are getting gas, there generally are not lines at gas stations.)

I'm going to contend you're exactly wrong, actually -- literally backwards.

For an electric car, routine fillups don't actually exist. You charge it at home and it's always "full" for commute trips.

Electric service station visits happen on long trips. Notably, so do bladder full exceptions and blood sugar shortfalls.
