I was at Menards today and they are now requiring face coverings to enter the store. They had a huge banner just inside the store entrance announcing the new requirement. (No idea why banner was not outside the store.) They also had an employee with a very loud voice letting everyone know about the new policy and letting people know they could buy a mask. I didn't check the price on a mask as I had a mask on and just wanted to get my stuff and get out.
The news media has been reporting that Costco will require face coverings starting Monday. I also stopped at Costco today for groceries, but after seeing the line of 100+ people waiting just to get in I decided I didn't to shop there that bad.
