I had an unpleasant experience yesterday morning August 3rd 2021 at WestJet from Winnipeg to Toronto. We got to the check -in point and was greatly delayed while attending to another guest for a long time, eventually it got to our turn but the customer service was asking questions that I believe they should have detailed and updated information on on a daily basis and should not be a base for delay. He also left us in-between to attend to the earlier guest despite the fact that we have limited time on a long queue.This action caused us to miss our flight. I believe WestJet just lost a customer. My lasting impression is the emotional trauma I left with.
