Wiley makes loud clanking sounds with his glass.
"Could you please not?" Raez asked.
"No not," Wiley said.
Raez tries to see if Rai has extra headphones.

Dion should feel free to do so as long as it's not too loud or something.
The waiter comes around saying, "Here are your egg rolls and noodles!" He places all three dishes down, somehow where each person ordered them, and told Rai, "Sorry, your order will just take a little longer!"
"It's fine," Rai said with a slight smirk. "I can wait as long as one of the others doesn't finish quickly and try to steal from me."
The waiter glances at Wiley out of instinct before just slightly nodding, possibly not coughing for dramatic effect due to overall hygiene. "Got it! Thanks for your patience. Did you all need anything else, though?"

He smiled back. "No problem!"
"I don't think we need anything else for now, but thanks," Rai said.
"Alrighty!" He shot a quick look at Wiley and Raez before just nodding. "Let any of us know if you need anything!" He took off again.

"I dunno, but it seems this restaurant doesn't lack in quality. By the way, think about what desserts you want, if any," Rai says.
"I'll...I'm good," Raez says, eying one eggroll like his last meal.
"I'll just add sugar to the water," Wiley declares, holding a packet up for emphasis. "Also, we all should go wash our hands. Mandatory."
Meanwhile, another waiter takes the menus politely but leaves one in the small book-like storage place next to the table's number card.

"Too bad," Wiley says, "you're gonna go wash your hands or you're not going to eat."
"Hand sanitizer isn't as effective as soap and water," Raez says, considerably in a gentler manner.

Rai gets out of the way to let him through. "You two can go with him. I'll look over the food."
"'Kay," Raez mutters, getting up. Wiley jumps up like there's a spring underneath him and takes off for the restroom.
He stops with a "Don't steal my noodles," before going off again.

"Well, towards the curtain over there," Wiley said. "That's usually where Chinese restaurants have their restrooms. By the way, the person symbol with the triangular bottom is the men's restroom."
Rai's making small keysmashing noises in the distant background.

"Nah, you gotta learn dependency. You find it first," Wiley said with all seriousness. "We'll follow."
While Raez has also never used for a Modern Sect restroom (or any public restroom, in all honesty), he's a bit more skeptical and it kind of shows on his face, but he's also uncertain. Downsides of being W.I.P.'s friend, you don't know if he's being actually helpful or pulling out all the bullcrap. In this case, he's pulling out the bullcrap.

Oh, how convenient, the "men's" restroom is the first one. 
"There's only two sinks anyways," Wiley is saying to Raez, who is still doing a semi-skeptical squint at him but doesn't do anything otherwise. "Let's wait for him to finish first."

Well, the sink's a sink. There's a lot of soap in the dispenser. The soap actually smells quite nice. The water is automatic motion-sensory. There are no towels, just blow-dryers, and unlike other "men's" restrooms in malls, there aren't any chairs or whatever. Since it's the "men's" restroom, there are no urinals and stuff. Just the stalls. No one's in there.

(I typed "soap" as "soup" and fixed it last second o.O)

The door creaks open sloooowwlyyyy.

One might not say so much as 'what' as 'who'. It's another person, with dim eyes and startlingly light hair, opening the door a bit and peeking in.
Well, that's not Wiley or Raez.

(We stan Dion's handwashing skills)

Well, they're kinda standing there, not doing anything more than peering in, and in fact the door is slanting more towards closing.

"...a..." They spoke. Actually they're a her, not a they. "...um..."

Well, at least his escape route is blocked, since she has a death grip on the door.
