Sir Cory, hope you won't mind my long post.
Since the kitchen part is the only part with big blocks of Japanese, I'll translate for you all what I can make out. (The rest of it is just "what is that?/A camera?/Ah! a camera's going round/Why have they put a camera going round? type stuff, like others have said.)
Kitchen staffer #1(glasses)- "Huh? What's this? There's a camera going round." Other lady off camera- "what's wrong?" 3rd lady, laughing- "hey- it's ok on a blue plate! (as if she's saying cameras are a blue plate special item, lol)"
Various staffers: "huh? what's that?"
Off camera lady: "The customer's inside? Who's (is) this?" Lady holding plate, setting it down: "There's a camera here someone may have forgotten! (she's being nice but stern about it, clearly irked)"
The first lady (in glasses)- "Yeah, that's it, they've forgotten it... (sounding concerned)" Walking away, holding camera on plate: "It's not raw (unintellegable). Coffee jelly for (customer) #30!"
Older lady's voice off camera again: "It still hasn't come (a response from the front staff[?])" Lady holding plate: "(I) haven't said anything (to them/anyone)" Young girl- "Really?" Camera plate holding lady: "Yeah" Older lady in background: "Put it back/out (the camera) this time- it's a mistake! (young girl laughing at that)"
Walking with plate- "Coffee jelly for #30!" RINGS BELL: "We're in trouble." Sushi chefs come. Lady: "This was going around and taking video..." Sushi chef- "Ah, this, it's probably a customer's. Umm, it's a foreigner." Lady- "they put it out (on here)?" Chef- "Yeah, they tried putting it out, to take (a video). Of the, er, of the scenery."
Plate goes round, back to girls- Sushi Chef to girls: "Oh, it came back, didn't it? (sounding nice at the end of a fun experiment, but slightly, ever so slightly irked at them, as if "ok, but please don't do that again, ok?)"
That's it. Hope my translation helps the fun a bit, the ladies in the kitchen were good sports about these girl's experiment. It was a rather rude but fun act, and they only got away with it because they were foreigners- the staff was nice about it, but the girls really should have asked first/known better. This kind of behavior is what makes Japanese sigh that foreigners are rude because they don't know any better...
That said, I thought this was friggin' HILARIOUS! Thanks for posting it- I live out near this area in Hokkaido ^_^
