I had 4 £12 travel vouchers from a refund, on saturday i got on a train at a unmanned station and wanted a £31 return so going to use 2 vouchers and cash but the conductor said the vouchers are not valid on train and must be used at a manned station so charged me £11 to get to manned station where i had to get off and go to ticket office then catch next train.Was he right i thought vouchers wouid be like money as there was nothing on them to say not valid on train.
