McDonalds at Sydney airport

I sat and watched this just before quite fascinated. Those of you a similar age to me, may remember big department stores had little canisters that the shop assistant would put account and money in and it get sucked away upstairs somewhere and n a series of tubing. It would alway come back with correct change and receipt. I especially remember Ballentynes in Chch had one. As a small child I was fascinated. This McD’s has the same sort of thing. Your order goes up a pipeline to the upstairs, and then a brown paper bag comes back with your food in it. Amazing to watch. I am so looking forward to my own b ed tonight. Thank everyone for messages. I really did appreciate them.
