Well of course not but that's not what I said

But if you want it a certain way there are just services that make less sense to utilize them.
Services are give and take sometimes. We get a crap-ton of plastic bags from ours like we don't understand why they put 1 one ounce taco seasoning in a bag by itself but they do. At least I recycle the excess bags back to
Walmart when I go into the store next.
But I wouldn't get out of the car to tell them to consolidate the bags. If it was like "nope can't deal with this many excess bags" we would just shop ourselves, we survived before curbside came around we'll survive after. It's def. a convenience to use though and we use it quite frequently although Walmart has upped it's minimum order from $30 to $35 now. So if I had a location around me where they don't do as much care into it I'm not going to get out of the car I'm just not going to use said service because I wouldn't want to deal with the worry over it. That's like going to the regular checkout lane like the olden days and have people who would insist on telling the cashier (or bagger) the groceries being placed in the bags certain way and certain order. The easiest solution is to use self-checkout but often those people won't by principle.
I'm 100% all for curbside online order grocery pick up. But when someone tells me that they don't want to be lazy by sitting in the car while someone is loading their groceries so they actively get out (during a worldwide pandemic no less) to get right up next to a worker (mask or no mask vaccinated or not vaccinated doesn't matter) so they can say they weren't lazy by either directing where the bags go or putting some bags in their car it's just sorta a contradiction. You're doing online order pick up for a reason those reasons you've listed out

For every employee that might be grateful for the assist there are ones who view it as you're in their way, it makes their process longer, etc (there's enough stories online to get both sides of that). I'm sure you've run into people who have been quite happy genuinely so and then others where you're the customer, you're always right and normal customer service behavior. Sometimes you'll never know.
Usually when people would view it as lazy they would just shop themselves regardless of the reasons. I know some DISers have expressed their negative viewpoint towards grocery pick up and they just shop themselves for the groceries. Anywho I get why you personally would want to do this but you quoted my comment where I said the point is to not get out of your car, curbside by design is that way. It doesn't make one a jerk (which is sorta the vibe of the other comment) to do something that was in line with the design of the service. If it makes you personally feel lazy I get it but it doesn't make people lazy by not getting out of the car.
