Props to making this on mobile, I know that can be annoying as heck. I do think the theme matches well and it's an interesting take, but the programming is too simple and there's really not much variation to the gameplay, it works as intended, it's just not very engaging, I think it certaintly would've been improved if you had, say, 3 clients and you could switch back and forth, but if you take too long to fill their drinks then they leave, or something like that. Anyway, good effort!
