LONDON, April 5, 2019 (BBC) -An independent coffee chain said it has seen sales fall by £250,000 since it banned single use cups last summer.
Boston Tea Party (BTP) has called for major national and international brands to follow suit.
Owner Sam Roberts said it had factored the loss in takings into its plans and that too many operators were "putting their profits before the planet".
Rebecca Burgess, chief executive of plastic pollution campaign group City to Sea, praised BTP's "bravery".
The chain, which has 22 branches around England and is based in Bristol, started the ban in June 2018.
