Input: Text: this happened about 2 hours ago. the prank was entirely inadvertent.

i felt like getting something to snack on from the service station, being that most places are closed on good friday. so i put my shoes on, put a jacket on, brush my teeth, use mouthwash, floss, and get in my car. 

within 30 seconds of driving i encounter a random breath test and me and the car behind me are ushered in to be tested. i am fumbling with my wallet to get my license and the cop says it isn't necessary and all he needs is my 'breath'. i jokingly respond something like "oh i guess i could give you that" implying i'm doing him a favour and he sarcastically thanks me in good humour. so i blow into the [breathalyzer](http://www.cmm.com.au/articles/wp-content/uploads/2011/07/breath-test.jpg) for about 5 seconds and he checks the reading. he is silent for a bit and i assume he's waiting for the reading to come up. he then asks when the last time i had a drink and i responded with "ugh like 2 years ago haha" and as i finished it clicks that somehow it's a positive reading. so i ask and he confirms and it's clear he is confused because the reading is ridiculously high. i realize that it might be the mouthwash i used a couple of minutes go, given i can still taste it in my mouth. i tell him this and he seems immediately convinced that i'm telling the truth and asks if i have a drink in my car to rinse my mouth out with. i find a nearly full bottle of [mountain dew](https://warosu.org/data/fa/img/0070/93/1382131029398.jpg) i discarded and gargle with it. i get tested again and the reading is 0 and he laughs and sends me on my way. the funniest part was it was clear that i hadn't had any alcohol based on how jovial and non-chalante i was about being tested, then realizing the culprit was something as simple as mouthwash.

edit: this happened in australia.
