Well what can I say. If you're not asking you're clearly not going to get it! Why not ask for a couple of each sandwich and see what you get? What not ask if there's an appetiser? How do you know it's at Kings Cross? I do try telepathy with some of my passengers but I've yet to have any success. If people are stealing the menu's simply ask what's on offer then ask if there's a hot meal.
You also know very well what the comment was geared at. Some people seem to think going to the Bar is beneath them, yes you are First Class but nobody on any train is that important that they are exempt from standing at the Bar.
On the subject of passengers, and how their minds work. Staff members walk through one will have two jugs the other carrying milk and an extra Tea or Coffee. You're then asked if you would like tea or coffee to which the passenger will reply yes I'll have tea please.... then stare at you. Now I can attempt telepathy to guess if you want Tea or Coffee but getting the cup turned upright is a whole other ball game, we're in Paul Daniels territory here. Surely it's not too much to ask that you turn your the cup over, is it?
Supply and demand yes but if the crew didn't take the temperatures of the modules anything in it was waste. So most likely 8 pints of milk, tomatoes, cheese, 20 butter, 10 flora, 8 panini's, 2 of each cold sandwich, 6 orange juice. Then the restaurant/dining stock so burgers, steaks, salmon, mash, veg, desserts. Now that's just one train. There are endless possibilities of how waste can be generated but mainly temperature checks and over-ordering are the two main culprits. Some of the dining stock was also only able to be refrigerated once, so once it's sent to the train if it isn't used it went as waste.
We also take the brunt of the blame when RG fail to deliver items. They have improved and the problem now seems to be them actually running out of stock rather than them failing to deliver it but I'm told there are some EC bodies also linked to shortages.
