That's a screenshot from Kevin Smith's Clerks, just two people talking which is really what the whole movie is, just people talking. That's not to say that this film isn't about anything, on the contrary, there's good reason that Kevin Smith owes his entire career to it. First and foremost is its dialogue. Often films struggle with dialogue that is expository and finding a balance with letting it reveal and develop character simultaneously, Clerk's couldn't care less about plot and rather than make the character's grow through circumstance, we're just watching who they are.
The dialogue's main purpose is to entertain just as we use it normally in our day to day lives, as if it is in substitution for the lack of money, sex, or violence we use to escape with in movies. Events escalate but they aren't connected, more so, one crazy thing happens then it's followed by a crazier event. The only moment of possible change a character goes through is in the end, where our protagonist becomes fed up with his banal and frustrating work life, it's relatable because of the film's grounded realism and the transparency that the director is speaking not to us, but with us. The clerk's friend explodes on him for complaining. Almost as if, if you had complaints about what the movie was, why did you stay? Probably because someone had something interesting to say.
