Actually, the milkman certainly exists today, in my territory I work people have coolers on their front porch for milk and fresh foods delivery.
Scissor grinders aka knife sharpeners still have the same mobile carts today and are very popular in farmers markets everywhere.
We have deer cullers across the street from me. They are sharp shooters and they cull the heard to a manageable amount. They have them everywhere where they are deer but hunting isn't permitted.
There are still food tasters, many political figures including Putin utilize one.
Family Video stores are still all over. Just because Blockbuster closed doesn't mean the rest did.
Cigarette girls are still working in nightclub environments in Vegas.
I quit scrolling through....
Thanks, Donald!
