Demanding sense is somewhat elusive. It refers to someone who is extremely picky and nitpicking. A persnickety individual tends to pay strict attention to detail and sets the bar high when it comes to expectations and flawlessness. Their attention to detail can be perceived as commendable, but it can also magnify extreme censure and avoidable dissatisfaction. Being persnickety is typically linked to meticulous attention to detail but can also be seen as a manifestation of perfectionism.
