In RP people shouldn't be randomly drinking things on the floor. Especially if it's contents are unknown. That's what research is for. Have it get disposed or quarantined then have a hazardous material handler help dispose of it. Try to get a dclass to drink it in the event it's something bad. You shouldn't risk your life drinking an unknown beverage. Sacrifice a life that doesn't matter. I agree with Gh0pit 100% here. There can be a lot done with RP. Many people complain there isn't enough of it, but things like how to properly address a situation in RP is one big thing that will bring out the RP in everyone.
I remember last year when i first joined, I was a D-class being taken to 008 for testing. The researchers did a very good job at roleplaying the dangers of being near 008 and even went into a full scale panic that a researcher left the door open when 008 was breached. "YOU MAD MAN, YOU NEARLY COULD HAVE KILLED US ALL!" I would like to see more interaction like that. Treat the cups the floor as dangerous and should be carefully examined if no one knows what is in it.
