The first time I used one of their giant touchscreen self-serve kiosks to order
Our Mcd's have these big touch screens also, although I hope they are cleaned often, can you imagine how many people might touch that screen in one day and the build up of bugs?
We also noticed that the staff have absolutely no idea who ordered the food only the area, so if a few people are waiting everyone looks up like meerkats when food is brought up!
