Can't go out of stock

Hi I have an issue with my vending machine program... Here is a link: https://w.trhou.se/r746h3m1js And below is the code:

sodas = ["Pepsi", "Cherry Coke Zero", "Sprite"]
chips = ["Doritos", "Fritos"]
candy = ["Snickers", "M&Ms", "Twizzlers"]

while True:
    choice = input("Would you like a SODA, some CHIPS or a CANDY? ").lower()

    try:
        if choice == 'soda':
            snack = sodas.pop()
        elif choice == 'chips':
            snack = chips.pop()
        elif choice == 'candy':
            snack = candy.pop()
        else:
            print("Sorry, I didn't get that!")
            continue
    except IndexError:
        print("Sorry! We're all out of {}!".format(choice))
    else:
        print("Here's your {}: {}".format(choice,snack))

The answer I get from my console is: Would you like a SODA, some CHIPS or a CANDY? If I enter chips 3 times, I will get this response:

Sorry! We're all out of chips!
Here's your chips: Doritos

Please advice if I missed out something somewhere? Thank you!

The code looks OK, and I get a different result when I run it:

Would you like a SODA, some CHIPS or a CANDY? chips
Here's your chips: Fritos
Would you like a SODA, some CHIPS or a CANDY? chips
Here's your chips: Doritos
Would you like a SODA, some CHIPS or a CANDY? chips
Sorry! We're all out of chips!
Would you like a SODA, some CHIPS or a CANDY?

Hmm, that's really weird!

Is it possible something changed after the snapshot was made?

No, I promise no changes were made after the snapshot was taken. :/

So is it still behaving differently?
