I actually feel like this fits the casino vibe of the 15th Weekly Note Composing Jam well too! But then again, shops and casino's have kinda similar vibes, so that means you're doing well ;). I like the little cash register sound effect and the sax, and the electric bass together with the - I guess - rock organ works well too. It indeed does end a bit abruptly, which can easily be fixed with a bit of fade-out or an ending cadence or something. The song has a nice vibe though, well done :).
