I came across a usage of the common word rider on a TV cookery show that I'd never met before. On checking, I found just two online dictionaries with the very specific definition
rider [noun] [UK data] ...
[c] a statement added to the contract of a performer saying what they would like to have provided in their dressing room:
- He requested only Pepsi and a few slices of pizza on his rider for a personal appearance.
- The singer's 25-page rider included "non smelly" cheese, six kinds of water, and five sofas.
[2.2] An amendment or addition to an entertainer's performance contract, often covering a performer's equipment or food, drinks, and general comfort requirements. [from 20th c.]
Given that M-W, Collins, OALD, Longman, AHD and Random House Kernerman Webster's College Dictionary don't mention the specific provision of extras (nibbles, drinks ...) for artistes (though the general 'extra stipulation' sense is of course well known), I'd like to ask how common this usage is, in the States and the UK.
