In the grander scheme of things, especially these days, this pet peeve of mine is a nothing burger. Yet it still kinda bugs me whenever I see it. And I continue to see it to this day after it first caught my attention during that scene in the movie
Sleepless in Seattle -- when Tom Hanks and Rob Reiner are walking down Virginia Street toward the Pike Place Market.
Tom Hanks has a paper cup of coffee. (From the original Starbucks in Pike Place?) It is supposed to contain some coffee but, to my eyes, the cup is obviously empty by the way it is being held by Hanks.
Over the years since, I often see in movies and on TV actors holding or drinking from a cup of coffee. But it almost always appears to be an empty cup, by the way it is being held by the actor. Or, almost as often, they will tilt a supposedly full cup of fresh coffee to their mouth by over a 45 degree angle, when in real life you'd tilt a full cup just a bit. (And it's almost always coffee--not milk or soda.)
