The Little Chef Lollipop was one of the most famous aspects of the Little Chef chain. Sometimes also called a hashlolly, it was offered to customers (primarily children, but also to any adults who asked) after they had enjoyed their meal. They were either placed with the bill, or in a cup on the way out.
The Little Chef Lollipop came in three flavours: raspberry, orange or lemon (which was originally available for a limited time but later returned as a permanent flavour), and had a sherbet centre. They had a distinctive Little Chef branded wrapper - in the early years it was red, while in the later years it would be clear with small Little Chef logos on it (most notably the 1993-2009 logo, which continued to appear on the wrapper until the chain's closure in January 2018 despite it getting new official logos in 2009, 2011 & 2016 respectively).
It's unknown when they were introduced (possibly the 1970s), however they were available until the very end of Little Chef in 2018. It also remains unknown who they were produced by, however a similar product has been made in the past by Kiddysway.
