I have just had the chap from the buffer come round and take orders for tea, coffee and snacks from the buffet. I have ordered a decaf (£1.90) to have with some of my biscuits. I suspect it is just the guy drumming up trade on quite a quiet train but very handy all the same.
You usually get the limited trolly selection or the announcement "due to the busy train there will be no trolly service".
