I was trying to buy something at Walmart, and this dude just starts criticizing what I'm buying like I asked his opinion!
Man I am so cheesed off today!
user
Oh really? Any reason why?
assistant
Yeah I was buying something in electronics and this guy shows up out of nowhere and starts criticizing my purchase!
user
Wow really? That's pretty rude and bad in general for an employee to be doing.
assistant
That's the thing!  It wasn't an employee, it was another customer!
