I don’t know if it was an urban British thing but the Arthur Treachers near where I grew up did a lot of walk-up business. They really didn’t have a large inside area and had maybe a table or two outside. The two locations I recall didn’t (and couldn’t) have drive-thru service because of how the buildings were situated.
