Bad Attitude from a consultant

I was at Belleville Intercape offices this morning to board an Intercape bus at 11:00. I asked the last that was at the front table if the bus that is outside is the 11:00 one she was so rude to me that the person behind me had to intervene. When they told her that she was being rude, she didn't apologize, she just got worse. We asked for her name after we checked and she only told us her name is Kylie. I understand that we sometimes have bad days but it is very unprofessional for a someone to bring their problems to work and take it out on customers because those very paying customers do have their own problems but keep them to themselves. Kylie needs to be disciplined, I believe she wasn't only rude to me because one of the older ladies in the bus with me is also complaining about her.
