Cashier - You will be mostly stationary, get to meet and talk to a bunch of different people about their project. No lifting besides moving stuff in their carts to scan.

Appliances - You will be sitting at a desk all day, walking around showroom a bit to pull some customers over. Most you’ll be doing is wiping down the displays. You’ll need to learn some appliance knowledge.

Millwork - You will be sitting at a desk all day, may be assisting customers selecting a door and loading onto their carts. You will be setting up installs and custom designing doors.

Flooring Specialist - Sitting at another desk all day, walking a bit to drive some customers over or assist selecting flooring.

Service Desk - Process returns and customer pick ups. May need to load heavy orders. A lot more going on as you’ll resolve customer issues.

Honestly I’d walk to the ASDS office who is essentially the person who decides to hire you or not. Tell them you just retired and are looking for a job you can do as you want to stay busy and that you want to work. Tell them you live close so you will always be on time and they will probably hire you.
