Would you consider this sexual assault?

What a fun couple!  

lmao! right! haha

Those chefs need sensitivity training...or actually just "don't rile up the redneck s***heels training". 

WOW... Shocking.. they're insane. ( SMH )

To answer your question... NO.

I would consider this a textbook example of two people raised on the mind-rotting pabulum of political correctness.  Two people who are in SERIOUS need of growing the hell up.

This is the kind of frivolous crap which makes light of very REAL instances of sexual assault.

No but it shouldn't be used in a restaurant.

No not sexual assault. It was water. Even if it was actually urine it would be a sexual assault. Assault perhaps.
Inappropriate for a restaurant certainly. I would not like that with my dinner.

NO some people are too sensitive and no fun.

I say setup. Couldn't get a good look at their teeth.
