Okay for a start, but there's a lot of key things if you're going to make this animation.
Since it's almost just audio, you NEED to make your audio as clean and as polished as possible. Not just so that you can understand what you're saying, so that ANYONE can understand what you're saying.
Towards the end there was a lot of mumbling, couldn't really understand what you were saying, was there a joke, or a punchline? Comedy or just a story? Couldn't tell. As well as inhaling, everyone gotta breathe sure, especially when telling a story, but you can edit those right out no problem.

I'd suggest you search for your own style, these minimalist drawings with hardly animation. Yeah, that's been done before. Not to say that you can't too, but if you don't wanna be associated i'd highly suggest drawing something that looks a bit more different.

And this is minimal, but it's probably something that just bugs me, and it's not anything to even do with your movie. It's the thumbnail.
The "WHOA LOOK AT THIS CHARACTER IN A WACKY POSE" along with the text, it's a very desperate attempt for clickbait. There's no real need to do that, especially here on Newgrounds.
It got me to click sure, but it was essentially to leave this review and tell you otherwise.

Overall i'd say try new things! This may be your first step but with animation you can do essentially ANYTHING you want, no need to copy joe-shmoe number one. Just make stuff you wanna make.

Oh hey! it's great to see theodd1sout make it to Newgrounds.

It's a good start, but I think you need to develop your own style. keep with it!

Damn, that review below me is long as fuck.

You have a pretty good conversation starter here. It's another almost tragic story of the human condition. On the waitress's side, she doesn't necessarily realize how well you know the usual activities at Pizza Hut, and she felt you had caught her finding humor in the situation, thinking you might take offense. That's the reason for the apology. She is not used to other cultures, and humor is a common "defense mechanism" for psychologically dealing with things we don't understand. It's easier to laugh about something uncomfortable than to deal with it quietly... And no, it's definitely not your fault she felt uncomfortable. Her parents and teachers (and others) did her a great disservice by not helping her understand that there are other cultures and customs and accents and everything in this huge wonderful (very weird) world.
Honestly, (and I've worked restaurants) she shouldn't have bothered you if you were at a table near enough to the front to realize when your order was ready. The only time to actually coerce customers into "proper places" is when the restaurant is busy. That's "Basic Customer Relations 101". And to avoid "weirdness like that" I've been known to order drinks for me and whoever came with me to get the food when I sit at tables to wait. Solves the problems of avoiding the wait-staff trying to tell me to sit on that couch, cause some of them are awful for sitting (like relaxing on a sharp stone)... So there's that little trick...
On the animation, good work... It's got the same vibe as Domics and several others on YT already, so you might want to check out the competition... Where you can improve is building on a library of looped character activities, particularly the talking actions. With that, at least when you want to have someone appear to be talking on camera, there's action already in the loops. It doesn't have to be Disney quality, just enough mouth action to sell that character talking on camera. You do a lot of talking, and lets face it, dialogue (and in the case in point here, monologue) moves the story forward most of the time. I honestly think working a few actions fluidly on camera will help you stand out from the crowd that already has a fan-base with this style.
The voice acting is on point, so you can decide for yourself whether or not to keep catching background in the microphone. It does that (in case you hadn't noticed) but there's lots of ways to get around that. Over all, you have a good sense of timing and you're doing some quality work for the style you're working with here. Take the time to enjoy it and get a thorough feel for it, but don't forget to grow as an artist and as an animator.
Finally, breathe, relax, and keep on keeping on. We're looking forward to your next post...
I'm just hoping to help along the way.

not bad for a first video :)
