Neptune Refreshments is the Refreshment Lady's main stall located at Lakeside. When on duty, Peter Sam would wait outside at the station for an hour every afternoon before he would take the Refreshment Lady to her "guaranteed connection" with Henry. However, Peter Sam accidentally left her behind once and she was not happy at all!

Since its original TV appearance in Peter Sam and the Refreshment Lady, Neptune Refreshments has appeared several times in stock footage and has also been seen at Norramby Beach in the eighth season. It has also appeared at Seaside Halt and near Knapford in CGI.
