Only 3 people or groups of 2 are allowed in at a time. As stated before there is barriers between you and the staff, but customers are allowed in only a small section of the store( less than 1/3) so it can get congested is there are more than 3 people. I would advise going in after learning what you want online so they can retrieve it for you.
All staff members wear masks and while they've created a small area in the front of the store for customers to shop, they encourage customers to order online and pick up in store. There are also shields at the registers separating you from the employees. It feels quite safe.
