One of the small, but not insignificant, things I do on road trips at the supercharger: As soon as I put the car in park, I'm opening the car door, stepping out and plugging in. Any time spent first fumbling around with a wallet, jacket, hat, checking my phone, looking at the route planner, gathering up trash, asking who needs to use the restroom or what snack they want, is all wasted time. Fortunately I have not yet encountered heavy rain during a stop, but the only added step then would be grabbing the umbrella from the center console.
I've taken four long road trips in my 2023MYLR. I start each early in the morning with 100% battery and an empty stomach. I also limit my liquid intake. This (usually) allows me to take advantage of the full battery and make the start-to-first-SC leg the longest. As others have noted, from the first supercharger onward, I'm only getting enough juice to get me to the next charger with about 10% reserve. For most stops the car is ready to go by the time I go to the restroom and grab snacks and a drink. If the charging is not quite done, it's a perfect time to do some stretching.
I do have to admit that if you are looking to optimize your time or your travel experience, an EV does take a little more planning and strategizing than does an ICE vehicle. For example, when I travel from San Antonio to central Mississippi, the Tesla nav tends to take me to the Nacogdoches TX V2 SC and then to the Shreveport, Louisiana SC. But the Shreveport SC (also a V2) is on the outer parking lot rim of a dying shopping mall that does not have a food court. The nearest fast food place is not a short walk and the neighborhood is a bit sketchy, especially at night. Also, access on and off the freeway is awkward. This will all be solved when the Bossier City SC finally comes on line several miles further down I-20. Until then, I will usually just spend several extra minutes at the Madisonville TX SC to get enough extra juice to let me bypass Nacogdoches and get to the Carthage TX V3 SC (for those who don't know, Texas is HUGE). From Carthage, it's easy to get enough charge to blast through Shreveport and get to the Ruston Louisiana V3 SC. The Ruston SC site has easier freeway access and much better walking-distance amenities than does Shreveport.
