Real Canadian Superstore review: I am complaining about the checkout station and clerk

My horrible experience with your check out system. A customer in front of me talked on and on to the clerk. then finally after paying moved to the end of the isle and started packing her groceries. The clerk started to put my order through sending them onto the other side. I HATE this system.
I had to go to the other side to start packing my order, the clerk then told me the amount of my order and made me feel like I had to pay immediately before finishing packing my order. So I had to come around from the other side pay and go back around and finish. I am 72 years old and find this unacceptable.
I told the clerk I hate this store. Her reply to me was "well you could go to a different store". I could not believe her attitude. My reply was she should not be saying that. Her reply was "well you are putting down where I work". NEWS TO HER: If I don't shop there she may not get a pay check. Especially if others follow me.
The next customer behind me started talking to the clerk(before I was finished paying and trying to find my credit card which I had out but put away while trying to find my optimal card. Frustrated at this time I hear from the customer how this clerk is working hard and has to put up with the crazies. This comment really hurt my feelings and more words between me and this customer took place. I complained to the manager who was as useless as could be. He thought he was in control but really just irritated me more. At the end he finally said he was sorry. I don't think he had a clue of how the clerk (2022/03/13)( Deborah 264) had spoken to me. My comment to him was that I would not shop there again and when he finally said I am sorry MY comment to him was"No you're not". Perhaps times have changed the customer does not have a right to express their concerns to the clerk. Truly I believe I am part of your payroll because without customers there is no store.
