I got a letter of recommendation signed by the PA and MD I shadowed at an oncology clinic. It is very strong but has two typos. The first is a "the" in between two words where it does not belong and the second is "and" when it should be "an". They sent me a copy and I feel bad telling them since they did be a big favor in both recommending me. Is this a big deal? I feel it isn't since it still portrays me as a strong candidate. Just want some opinions.
