The vibes are very excellent here. You nailed the mood of a chill jazz bar quite well. I think anymore than the two drinks would get pretty chaotic, so the balance here is well done.
Some small critiques I noticed:
* You couldn't abort a drink once you started. If I accidentally triggered "make cocktail" when I wanted to talk to a person... well I guess I'm making a cocktail now
* I wish the cocktail shake bar went away after you were in the green. As-is, I had to mix all the way to the end but the indicator makes it seem like if you go over that's bad
* I think drinks disappearing in front of you after you make them isn't ideal -- I wanted to immediately take the drink to a customer but I had to take extra interactions (and risk clicking the cocktail mix!) to get there. I'd love if the beer went to your hands instead, and you had the option of setting it down if you wanted to "store" it
All-in-all, quite moody and enjoyable. Well done!
