There are effectively none, since any protections are thrown straight out the window given that they touch and handle your card to process your payment, instead of allowing you to tap/insert it yourself.
All employees were wearing face coverings. They have a curbside option if you don't want to go in. The manager on duty was so awesome and was actually holding and opening the door for people, in and out, so they didn't have to. He was also bringing the food to people instead of calling names for them to pick up at the counter.
