I put "Thanks and good morning" and it said it was correct but "Thanks and have a good morning" is acceptable also. Is the "have a" simply understood to be in the sentence? and which one is more correct. Obrigado!
To me, "have a" is not implied. They are both perfectly correct sentences, but they are often used in different contexts. I would say "have a good morning" is said only if either the speaker or the addressee is leaving, but "good morning" can also be a greeting.
