I worked in a National Food Store about 60 years ago. Stocked shelves, changed price stamps/stickers on products, weighed and marked your produce (added a few cents if I had seen you snacking on the fruit), wrote the refund slips when you returned bottles, and then had to sort all the different bottles to get them back to the right places.
Back in the day when I had a paper route (about 65 years ago), several of my customers who had big evergreens in their yards put strings of Christmas lights on them and left them on all year, just only turned them on around Christmas. Don’t know how they got them up to the top or how they replaced burned out bulbs.
I used to live in Milwaukee and remember when they first put it up. Supposedly, that is the way it is done in some countries. Makes it easier to place the presents under the tree.
Look at the roof top. They went around the neighborhood, getting the snow off the roof to reduce risk of the roof leaking.
