Even those that serve lower end wine worry about it. (Our max bottle is $14ish wholesale). I run a brewery that also serves wine and our bottle loss is a significant enough percentage of our total wine sales, because of our low throughput. It commonly happens that a bottle goes "bad" with only 1 pour from the bottle thus returning a loss on that bottle.

Even with the bottles that leave two pours, at expiration, we are making a few dollars but not enough to keep the lights on.
