Annoyed customer

I am absolutely disgusted with what happened to me today. I have been with this bank for 10 years and never had an issue but what happened today has got me thinking twice. I had to wait for 30 minutes to get serviced. There was no queue but only one consultant available to help with applications with what I needed. When someone eventually became available to help me, I couldn't even get anything done because I ran out of time and had to leave. I would've understood if there was a queue but I was the only person waiting to be assisted. I don't understand how you can have only one consultant at 14:50 to help.
