Trader Joe's review: Covid protection for lines of consumers

The Trader Joe's in Ann Arbor has some excellent policies and others that could use improvement. In this case we are all learning how to deal with the Covid problem and many of their solutions were good from the first. However, there is no sign outside specifying you must wear a mask when in line. This results in customers waiting to put up their mask until they are about to enter. And there is no sign showing what is correct for the mask, as there is at Whole Foods locally. If customers in line leave their mask covering only the mouth, they are not protecting anyone, including themselves. I've seen this problem enough in the Trader Joe line that I believe the problem should be fixed. Signs could adorn the brick support pillars all the way along, or one large sandwich board sign at the entry might do the job.
