No Aircons, No Service, No additional tills

It was a hot summers morning, Saturday 10 January 2015 when I needed to purchase one school shirt for my son. We were standing around for 10-20 minutes with no one even asking if we were helped. The queue was very long and not going fast, in a heat wave. Eventually I reached the front of the queue and heard the owner tell a customer that if she wanted service then she should be there at 7h30 in order to be individually served. As I reached the tills I told the owners sons that they should tell their father that he should invest in aircons and also listen to the customers in getting more people employed over busy times to service the customers. I also told them to invest in more tills as three till weren't enough, whereby I was told by the owners wife to get out of their shop just after they took my money. This clearly shows that my money was good for them. But they do not want to listen to advise.
