I heard the incredible figure of catering sales fall since iet was introduced! Not because people don’t buy from the trolley, but the trolley can’t get through a crowded train, or lack of staff means only half a 2 x 5 has a trolley
I've been on plenty of
IET▸ services on which a trolley would have no problem getting through, on which I'm reasonably sure that a trolley went through, but I have no really recollection, because the contents of the trolley hold little appeal.
To be honest I'm fairly price insensitive, but if I want anything, it's a proper cup of coffee and a bun, or a good sandwich, neither of which the trolley (or even a buffet for that matter) can sell me. So I'll go to Caffe Nero or Pret before I get on the train, and only buy from the trolley
in extremis - I suspect that's the same for most other travelers, with for most, price being an even greater determining factor.
Leaving aside the >3 hour services where it would be nice to have a decent hot meal with tablecloths and cutlery. In my ideal world there would be the equivalent of a continental kiosk, with a decent coffee machine, from which (depending on my inclination), I can get a decent cup of coffee, a beer, a glass of wine, a G&T, a toastie, a sandwich, a croissant, a chocolate bar etc.
But:
1) I'm not entirely sure that there are enough people with tastes like mine to keep it busy
2) The economics almost certainly don't work to provide one per 5-car
3) Lots of people won't get up out of their seats to find it, because they don't want to leave their stuff, worry that they'll lose their seat etc
4) You need to provide an offering that is comparable in quality to Pret, M&S etc.
5) You need skilled, motivated staff to run it, keeping it clean, stocked, avoiding wastage etc. It's a fiddly job.
6) You need to do all that in a way that is profitable
7) A buffet is probably going to take up the equivalent of at least 8 seats, so you've got the loss of revenue from them to cover.
To be honest, I'm just not sure that it's do-able, and that a cart is probably the most pragmatic solution of all, until you get to 3 hour+ journeys, at which time it is sensible to offer something else.
