The old saying holds. Owe your banker £1000 and you are at his mercy; owe him £1 million and the position is reversed.

If you owe your bank manager a thousand pounds, you are at his mercy. If you owe him a million pounds, he is at your mercy. | If you owe your bank a hundred pounds, you have a problem. But if you owe a million, it has. | As quoted in The Economist (13 February 1982), p. 11
