Long queues that don't seem to move can be frustrating.
In places where long, straight queues tend to form, a horizontal escalator that moves slowly away from the teller for a brief time, at short, regularly spaced intervals would give one the sense of moving forward. A slightly less unpleasant experience.-- shudderprose, May 05 2009 //I think the device you're looking for is called a slidewalk//
I think slidewalk and horizontal escalator are synonymous. Unless you're referring to the fictional sort, in which case this wouldn't do. The stop-start feature of the queue stepper is designed to mimic the natural progression of a queue. H. G. Wells' slidewalk is constantly moving, as far as I understand.-- shudderprose, May 05 2009 better have the teller move backwards at intervals. That way one gets to see many parts of the city in long queues.-- loonquawl, May 05 2009 random, halfbakery
