You get a lot of this with slabs, in my experience. Climbers padding around fairly comfortably, no hint of forearm pump, at worst a bit of discomfort in the calves and toes. It is tempting to think "this feels too easy for ....." What they might not be doing is realistically assessing the consequences of a fall, often from some distance above marginal gear.
