Actually sir...

"Actually sir there is something that I need to comment on..."

Something had to be done about this whole thing, and the idea formed in my mind.
"My parent is fine with me drinking ****, but I know you're not, and someone spiked the drinks here..." I lied, finding an opportunity to halt the night and taking it.
"Oh wow. Thanks for telling me. I'm coming to get my Jasmin." He said, taking a pause.
"And $name. I suggest you leave too. Such a setting is not ideal for you." He commented, before adding:
"Thank you for letting me know about this."

He hung up, grateful for my intervention.
I just snitched on my friend... With a lie, but nonetheless...
