Do you think I was rude to this girl?

I went into my workplace on my day off and I was sorta tired but my female coworker was being super friendly (but she looked a little uncomfortable since I wasn't talking much) and asking me questions like why Im there... Anyways as I was leaving she said have a great day and I just said cya... I should've said you too1er giggle and say "didn't care" I assume they were saying I acted like idgaf. I assume that cause the store was dead and there was nothing else going on.

. Was I rude or awkward in your opinion?
