any port in a storm

Any port in a storm (as the sailors say) (in an emergency, we will accept help from any source and in any place, even from an unpleasant person; if you cannot get what you want, get what you can) — на безрыбье и рак рыба; выбирать не приходится;

Example 1: I don't even like him very much, but I had to move out of my flat and he offered me a place to stay. Any port in a storm, as they say. (CIDI)

Example 2: "I'm afraid I've run out of coffee. I can only offer you tea." — "That's all right. Any port in a storm."
( ...Ну, тут уж выбирать не приходится.)

------
We use this expression when something that we want or need is not available and we must have something else instead. Beggars can't be choosers has a similar meaning
