Remember when we were little kids and our parents would take 35 MM pics of our foods, get it developed at the fotohut and then mail it out to friends and family?
Me neither.
(guilty of taking pics of food)
Well, consider the process of 35mm photo taking: you had at-max 36 shots with no delete/preview. Kitchen lighting tends to suck, and after buying the roll of film, you had to get it developed and then and only then could you see if your shots hit or miss.
With digital you can take over 1000 photos per memory card (depending on the camera or your cell's spare memory capacity), and you can preview/chimp/delete to your hearts content--not to mention low-light capabilities far beyond your average roll of Kodak.
It's no surprise that because of the instantaneous review, plus the quantity of shots taken, plus the ease of sharing .jpgs, and plus the ease of just about any enthusiast-level camera to get a decent image without knowing anything about photography means that stuff like food photography, selfies, etc. was bound to become a thing...since it's easy and cheap for anyone to do.
I didn't realize it was common for people to put milk in their omelets. I've always just cracked 3 eggs, put in some veggies, choice of meat/fish, salt and pepper, beat it, and then pour over a heated pan of olive oil. Flip it midway through, and then serve with toast.

I find milk can make it a little fluffier.
My usual omelette is about 2-3 eggs, beaten with a little milk. Pour into the pan. sprinkle some seasoning salt (Johnnys) and tabasco, and then add the meat/veggies/cheese. Cover to let the top start cooking. Then, once the top is mostly congealed, fold in half, let cook uncovered for a minute or two. Flip so the otherside gets done, then serve.
