their warehouse picking system was descended from an old mainframe greenscreen app. the kind where you have a terminal connection and you have to put text in the different fields. when they upgraded with new systems it all tied into that same old backend, parsing the fields from their known positions in the terminal output.
this occasionally causes interesting problems. most spectacularly when someone ordered a large reel of solder and something overflowed a text field shifting everything down.
this resulted in the item price being parsed as the quantity.
the customer phoned them up when a haulage company unexpectedly arrived carrying an entire euro pallet of solder.
with a waybill saying that this was delivery *one of three*.
they didn't have enough stock at the main warehouse, so the system had sent a request out for another two trucks to bring more pallets of solder from their EU warehouses.
