one check-in crew (female) at gate was not very nice. My mom is disabled & in her personal wheelchair. The other check-in crew members told us (5 total) to go together to board the plane then this female staff told us we can only have one family member go in with my mom (to take care of the wheelchair then assist her on the plane) next time we board the plane. Their messages are inconsistent & her attitude was uncalled for, especially when she let other disabled passengers on with their more than one family members & the other Asiana staff members told us to go in at the same time.
