Prov. If someone gives you something you asked for, you should not complain about what you get. I asked Joe to lend me his bicycle, and he sent me this old, rusty one. But beggars can't be choosers.Jill: Let me wear your green dress; I don't like the blue one you lent me. Jane: Beggars can't be choosers.
something that you say which means when you cannot have exactly what you want, you must accept whatever you can get I would have preferred a house of my own rather than sharing but I suppose beggars can't be choosers.
Those in dire need must be content with what they get. For example, The cheapest model will have to do-beggars can't be choosers. This expression was familiar enough to be included in John Heywood's 1546 collection of proverbs.
