Boyes shop in Hull on Hessle Road had the zipwire system to a central cash desk overlooking the whole shop.
There was also a vacuum tube system which was still in use in the early 70s when I worked at a car spares & repairs place.
The people in the workshop would put the payment and customer details into a cylinder, insert the cylinder into a brass tube, press a button and, with a loud 'Pop' of evacuating air, the cylinder would be sucked up the tube, through the ceiling and land with another 'Pop' at the end of the tube beside my desk.
I would then issue a receipt and any change due and despatch the cylinder back to the folks below down a parallel tube.
At one time, I was having a bit of a thing with one of the mechanics and when things were quiet we'd send each other little flirtatious notes up and down via the tube - until his boss intercepted one and pinned it up in the locker room. 🤫
