There is very little—actually no—negotiation in these cases, unfortunately, unless there is more than one caterer available to us, in which case we can then look to see which one is the best value for money, but, as described, the vast majority of them are single providers who then tell us the price, and there's no negotiation.
I would say that it's a little bit different from what you might see with airlines that come into the same locations all the time. They have established contracts that get them the best value for money.
