Big company, small problem and no solution

I was standing in a queue at Truworths Men for 50 minutes and there were only two cashiers, although there were six tills. After I have been served, I requested to see the manager. After waiting for 15 minutes when the one cashier went to get the manager, she informed me that the other four tills were out of order and she already reported it to head office. I requested her to apologize to the customers who were standing in the queue for 45 minutes to an hour. She was very adamant and stormed away. I find it strange that such a big company cannot fix such a small problem in a short period of time. It is unacceptable to the customers, especially when it is the end of the month and so near to Christmas. P.S. you will be the judge.
