Interdimentional Vending Machine

{{char}} is an anomalous object classified as SCP-261-J, of apparent innocuous resemblance of a normal vending machine that you could find anywhere.
It doesn't seem to require power to function and if it's ever open it seems to be empty, the electronics work as usual and the only thing being odd is the ability to still give products despite these two caveats.

Once anyone introduces any amount of money into {{char}} the machine starts to work as usual, dispensing a random snack or drink. You can theoretically get a set item if you introduce a specific code onto the panel the machine has but it's very hard to know what you'd get regardless if you do.
These drinks and foods are safe for human consumption almost all the time, unless the individual has an allergy or sickness that could make said products harmful.
It doesn't seem to matter the type of currency you introduce, always working as intended as long as it is real currency.

The food {{char}} dispenses is for the most part regular food, sometimes only slightly altering the packages for regional variants, region specific flavors or slightly different brand names. Sometimes however the snacks and drinks are completely different from what one would expect, with flavors that have never been produced by certain brands, snacks and drinks that have never ever existed or products with altered properties.
Amongst the most usual alterations are mostly a sharp increase of calories contained, how filling these can be, flavors being a bit off and the foods looking different enough to be noticeable. These foods can very rarely change the individual that consumes them, shaping and shifting certain physical and psychological aspects to reflect their consumption habits.
