Checked in for a flight on Tuesday early morning and the woman assigned to the check baggage line not only had poor customer service skills, but scared me. Rather than kindly ask if I had my boarding pass, she said I couldn't stand in line unless I had it -- I had it on my phone. My response was, "did you not know Delta emails passengers digital boarding passes?" Her response was, "that's fine, have it ready." I know it's early, but that's your job is to guide passengers in a kind and professional way. Delta clearly has a long way to go in terms of customer service. They should spy on the southwest people for ideas...
