I’ve done it a few times mate, sometimes the lakes all stitched up and the only places left you wouldn’t want to sling a rig in, good judgement sometimes means you leave it for another day pal. I’ve found that if I end up in an unfancied swim, not been happy with it, not done a carp in millennia, I’ve not felt confident, not fished to my best and blanked… I suppose I’ve defeated myself before I’ve started, fished like a Wally, expecting to blank - then do so, thus proving to myself it’s a waste of space swim in the first place… a self fulfilling prophesy you might say!
