How do you all do it?
"My" aeroplane is even smaller (C560 without XL). In one of the drawers there are tea/coffee cups and teabags, milk and sugar, in another drawer are glasses: 8 wine glasses inside 8 water glasses. The remaining drawers contain various kinds of beverages.
The food (cold meals and snacks only) is pre arranged on trays which are stored in catering boxes that we either belt to an unoccupied seat or under the coathangers in the back. We place company branded cutlery and napkins on these trays before stowing them. Beware of ramp inspectors, they don't like to see unfastened boxes in the cabin - this is one of the first things they look for!
If that's not good enough for your passengers, you can politely point the to a good restaurant, after all our business is transportation and not feeding... And if they really want to dine with style on board of an aeroplane, they must buy or charter something two classes higher.
