Today, after studying some CS241 with Alan, I went to buy some drinks from the nearby vending machines. I bought my apple juice for $1.75, which is normal... and then I went to buy Coke for Alan. So, I start inserting the coins... quarter, quarter, quarter -- then the machine got jammed!
I go back to Alan to tell him about his misfortune, and we end up going back to the vending machines. I tell him that it's jammed, but Alan, being a tad stubborn, wants to insert another quarter (a special one called "Wisdom").
Jason: "I wouldn't recommmend wasting another 25 cents Alan."
Alan: "Just let me try it."
Jason: "Okay then."
Alan: "Here goes Wisdom!"
*Machine eats the coin*
Jason: "Told you!"
Alan: "Oh no. Damn vending machine."
I decide to head back to studying. Apparently, Alan then decides to spend $1.25 on a can instead of $1.75 on a bottle. So, he goes to the adjacent can vending machine and tries it. After 75 cents, it also became jammed. Alan puts in a penny in an attempt to unclog it, and it worked! He inserts another quarter, and the machine jams again!
Alan then goes to another bottle vending machine and spends $1.75 on a Coke bottle. He comes back and tells me about the can vending machine and his bottle. Alan paid $4.20 for his Coke!
This reminds me of when I got screwed over by vending machines in high school:
*Jason deposits $2 into the vending machine*
*15 minutes later -- a girl walks by and buys a pop from the same machine*
*Jason decides that the machine now works*
*Alan and Raymond advise Jason that it's not worth it*
*being stubborn, Jason deposits another $2 into the vending machine*
*Jason feels rejected for the rest of the day*
Conclusion: Vending machines should be more reliable!
