In my area, they mostly didn't bother with plexiglass between tables, for a number of reasons (there were some really major questions about the effectiveness of those measures, for one thing) Instead, most local towns made various changes in ordinances to allow restaurants to have more outdoor seating.
Here it’s a government sponsored thing. If you plexiglass up, restrict seating and whatnot, the gov subsidized the cost.
