Narrative:

Guest boarded with a face shield only. Approached guest and inquired if she had a mask she could wear in compliance with the policy. Guest I guess was having a bad day but initially pushed back asking when that had started. Informed her we had started this policy on the [date] and we had masks on board to assist with. She indicated she had her own cloth mask. Don't allow guest onboard without proper face masks. Makes it very difficult to work and gain complaints onboard.
