  1. I'm a vending repair technician! Went to 4 years college and make 150k a year! Sucks ballz getting paid in nickles amd dimes tho! ?

  2. Once, I was waiting in line to get a snack from the vending machine and there were only 2 people in queue, me and a teacher from my school. She ordered her snack and 2 of them came out, even though she had ordered one. She recognised me and gave me one☺️??

  3. One time I got coke for $1 and right when I pressed the coke button I pressed the button that gives you your money back and I got $2 dollars back

  4. The second one about the lasers is a lie I got two one for free and one I paid for and the one I paid for touched the lasers and I still got the second bag that happened to me two times

  5. My friend bought popcorn. Got caught and didn’t come out. Problem was it was hitting the lasers and still caught onto the hook. It took a few kids running headfirst at it to get it out.

  6. A year ago: YouTube recommended this to me.
    Few months later: I watched this again.
    Today: FINE I’LL WATCH IT FOR THE 100st TIME!
