You should not have to apologize to someone when they do their job. Their job is to reward you with these points and until they do it consistently, they deserve the many emails. If you don't do your job and get chewed out by the boss, or if you have someone working under you where this happens, you don't get an apology or give one to your worker when they do the job the next time. This is their job. They are supposed to give us the points when we earn them. There should be no apologies given when someone does not do the job they are paid to do.
