Conundrum

So literally just moments ago, I was in the elevator and a boy popped on.

"Hi," he said.

"Hi."

"Do you like Starbucks?" 

"Um, generally." (I need to work on my over-dependence on the utterance 'um.')

He then proceeds to produce this tasty looking fella out of thin air (an exaggeration, I assure you.)

"Do you want this?"

I note that the cup says Eric.  

"Um, How do I know it's not poisoned?" 

"You trust me."

"I do?"

Well, long story short I took it.  But now, do I dare drink?
