It is common courtesy to be on time for appointments and events but some people do not care about being punctual which often leaves the people who are always on time waiting around and feeling irritated
Context: "Sucks to be a person who's on time dealing with people who don't care about being on time themselves." Claim: "It's really irritating when people who are always on time are constantly waiting for the others who don't care about punctuality"
Considering the context, is the claim true, false, or unknown?
