"A Quiet Man" first few pages...

[John Oberon]

Yes, it would be; there are more efficient ways to move characters about than larding your prose with a lot of GPS instructions. That said, you have to give the reader a transitional phrase or sentence to prepare him for the shift. How exactly is up to you, the writer. (That's an important function of editing: to read your ms from the eye of a reader who doesn't know what you the writer knows. It's a skill you should develop if it doesn't come naturally.)

In your piece, your first few paragraphs are set in the convenience store (John is correct in this). Then you have a transitional line, but perhaps it could go a tad further. Here's what you wrote:

I somehow managed to score the next couple days off, which only meant one thing: cheap vodka and cigars.

That clearly indicates a jump in time and setting. If you had added something like, "meant one thing: cheap vodka, cigars, and time alone in my room", you would have taken the reader into a different time and place (and satisfied John's pedantic definitions).

Moving characters around quickly and smoothly (I call it "staging", as in a play) is difficult because it's hard work to make it seem invisible. When you clutter it up (yes, you got it right) with a lot of he walked down the street and opened the door to the building and climbed the steps to his apartment, it becomes intrusive and boring.

Let's see....we just spent four paragraphs in this MC's mind with no jumping to a different time or place, and you think this sentence, another thought from the MC's mind, is a clear and literal jump in time. And you think this after the tense switches from past to present and back again several times. Somehow, you think that because a character starts thinking about a different time or place, it indicates a literal transition to another physical time or place. Odd I've never seen anyone practice this unusual skill in my life. Perhaps the MC lives in a world where people can mentally teleport themselves to different times and places, but I think not. This piece doesn't strike me as fantasy or science fiction.

Sorry. At some time, the MC has to physically go to his room, not just think about it. Or, he can think about it and still be in the convenience store or some other location that he physically travels to. One or the other. And it needn't be intrusive. It can be as simple as "I went home after work."
