bad service and lack of professionalism

This morning I got to Pep Stores at 8;56am, there was a guy who was opening the roll up security doors and at 9 oclock all the cashiers went in and closed the door behind them. At 9:05 their supervisor also came passed us and went in. I then asked one guy who was standing inside just by the door if I can come in cause I'm in a hurry and the store is supposed to be operating by 9am he said I can come in if I want but he will lock me inside . So we continued waiting outside and there number of ppl outside was getting more, others left . When they finally opened at 9:22 we all came in. Now my biggest problem is how this people are trained to deal with customers. Shouldn't the manager apologize to a group of people that are waiting outside with their money. I asked one staff what was the branch, he refused to tell me the store name. So if Pep stores opens at 9, shouldn't the staff be there before 9. So that by 9 they systems are up and running. One staff member even came to sarcastically offered me to come and use their phone and call head office if I wanna know the branch name. If you having system problems apologise to instead of being bigheaded like you doing us a favour.
