I used to judge parents who resorted to tablets to keep their children quiet. I don't really anymore. You don't know how exhausted the parents might be or how many hours they've already spent trying to entertain their kids in a more wholesome manner.
I've taken a 2 year old on vacation and some of that time is spent going to unique restaurants that take a couple of hours for a meal. My toddler would get bored and squirmy and would quickly ruin dinner for the entire restaurant. Same thing for airplanes. Of course I don't resort to it immediately but if talking, interacting, and other toys don't do the trick, iPad is a very useful tool in the arsenal. A carefully curated list of educational, offline content is acceptable in my opinion.
Grocery store, or any other short errand? Sure, that's too much.
