Paid 1st class as a treat to myself as just retired & assumed refreshments would be supplied. None. Had to leave my seat in carriage 8 at Salisbury due to removing carriages 7 & 8.With all luggage, walk up the train three carriages to find another 1st class seat. No buffet, trolley services or aircon (27 degrees today) on a 4 hour journey from King's Cross to Exeter. Told at information no service since covid, that was years ago. No excuse now. Such a let down. No staff in sight. No notification at King's Cross not to use carriage 8 if going past Salisbury!!! Why not??? Simply lazy customer service. Earlier train LNER from Grantham to King's Cross 5 star. Trolley service & waitress FREE coffee, alcohol, soft drinks, hot lunch menu, crisps & biscuits for the 1st class price of an extra £18 for a 1 hour journey.
