Well, I got into snotty email mode and sent this...
"On Sat 12th April I travelled from York to Stevenage and back for a day out with friends, with my bike. On the return leg, I arrived at the station with 5 minutes to spare, and was unable to find anyone on the platform to let me know which end of the train I should be at in order to load my bike. When a member of staff did appear, just as the train was approaching, I asked and instead of receiving a simple instruction, received a rather curt "Is it booked?" I would be interested to know if all passengers making enquiries are first asked it they have a valid ticket, or if this is a service you reserve for cyclists. Having got on the train, and been made to feel like rather a nuisance, I had a trouble free journey, until I arrived at York. I took the trouble to walk down the train before arrival so as to be on hand to unload my bike quickly, but there was no member of staff in evidence, despite an assurance from staff when I boarded that they would 'let York know', and it was some moments before I attracted the attention of anyone - leading me to worry that the train might leave with my bike still on board. I travel with a bike on the East Coast Main line at least twice a year and always do my best to take the minimum time loading and unloading my bike. This is the first time I have had any cause for complaint, and coincidentally the first time I have travelled with my bike since GNER were replaced on the service. I realise that it may be an isolated incident, but I feel that some of your staff might perhaps have a more positive to attitude to passengers with bikes."
It's not great prose, I know, but it's hard to be artisitc in a fiddly little email box.
I note they also have the standard marketing thing about "if you don't want us to pass on your details..." and it says "untick this box if you don't want us to pass on your details" - the box is ticked by default and the vaguely double negative nearly had me flumoxed...
Perhaps I've been spoilt by all the trips to Berwick, where the staff are fantastic. One poeter once stopped me on the footbridge to tell me that the bike would need to go to the other end to normal - I didn't ask - he just saw the bike, made a connection in his brain, and gave me unsolicited helpful advice... How old fashioned...
