Bad attide and bad custome service

1) I visited the Jet Mart store in Ranburg on 21/05/2015 at 1:30pm to pay mom *** and buy.when I got the the cashiers there was only one cashier on duty and found two ppl infront of me and eventually 4 more people were behind me( I started talking loud about expressing my unhappiness and how on earth 20 tills and one casheir..2) while I was talking I asked the lady next to me where the manager is cause I wanted a complain about the slow and long que she pointed at Thabo Maje who was wearing the Management long sleeves T shirts .I started talking loud saying that I believe If he was the manager he could have at least apologized to us for the long que and maybe explain that we should be patient as the staff might be on lunch and I said I believe he is just wearing that T shrits he just be the manager cause everyone was expressing their dissatisfaction regarding the long queue loudly.3) When I got the till (the cashier was Khuselwa & Thabo Maje came and said to me thanks for insulting him cause I he overhead the above conversation him wearing management shirt and said niks abt my dissatisfaction.4) Did I insult him ???I will never go there..no open account
