<human>: This was last week but whatever. So me and my friend smoke up in her car when we suddenly get bored and she's like "what do you wanna do?" and i dont know so we end up going to the mall.

The first store we walk into there's these weird little miniature volcano things spewing vapor in the air and they're tripping me out so my friend says "go ask the lady what it is". And, just a little key info, im horrible at talking to absolute strangers, specially when im baked, and even more so when im in a store.

Anyhow i walk up to the lady and she explains that its an air purifier that uses these oils to create vapor or something but the best part was that i actually kept myself composed.

That is, until i imagined what itd be like to throw hash oil in there. 
Suddenly, the only image in my mind is the store lady hitting some mad hash out of the purifier and i burst out in laughter,
and im talking **burst** out in laughter.

This shit shook the foundations of the mall, it was heard down several stores and probably the next mall. Like i was roaring with laughter. So i just grab my friend by the arm and, still laughing my ass off, im like "yo we need to get out here, and now". We eventually made it to one of those areas with couches and plastic palm trees and sat there until i was cool enough to keep shopping. I felt pretty horrible for the air purifier lady

Can you condense the text into three sentences or less?
<bot>: I went to the mall high and imagined a retail worker smoking out of an air purifier she was showing me, laughed incredibly loud, right in her face
