Sorry to say
But I'm pretty sure this isn't true.

The descriptions on the tills aren't controlled by the tills themselves but by a central computer either on site or at another location.

Sorry...

Good story tho

God I'm bored

Not strictly true
The shop I work in (part time) has an EPOS system which allows changes to the free-text descriptions and other details on the receipts. Can't modify cost/markups/prices or product codes but we can change a lot of the other bits on the printout :)

More importantly
why would anyone bother making this up?

it's amusing if true, but making it up would be pointless

To be fair
it was a sweeping generalisation and as stated I was bored...

and I only ever worked in 1 large store!
