I like it! One language was obvious (and I noticed another later), and it helped me to figure out what was going on. It took me a moment to realize that I could fill in to find out. Very helpful.
I will say that I would like more variety of phrases. Each customer repeats common phrases and I think it would be more fun if they talked differently, maybe upscale, or British, or something to indicate a different language.
I liked it. Great game!
