Voting and going to the grocery store are pretty different in multiple ways. For one thing, we give people exactly one day for in-person voting, and they don't get the day off from work - so they probably have a total of maybe 5 non-work hours available to them during which polling places are open, they go to one, stand in line with thousands of other people, then walk into a crowded place, interact up close with polling staff, and then interact up close with polling equipment. The polling equipment is not frequently sterilized (if at all), the polling staff might not have protective gear, and the polling places are cramped and poorly ventilated. It doesn't matter how many people need to vote there - 100k? 1k? same difference - you've all got to do it today, and in these specific hours. Sounds really safe! In comparison, you can go to the grocery store whenever is best for you (as long as they're open - and many are open 24 hours any day of the week), there are lots of locations to choose from, and if you go during off-peak hours the aisles are relatively empty and you have enough space to social distance from the other people in the store. At this point, the staff typically have masks+gloves and there's often hand sanitizer and cough shields. Some grocery stores explicitly limit the # of people inside at any given time.
