Bad service

I am far from being happy, The service I got from Sheet Street south Gate doesn't make me happy at all. I get to the cashier and had planned to pay with my Mr Price card. The cashier that assisted then asked if I have my ID or Drivers Licence, I rep**** with a No. I only had my phone and purse with me. She then said "I'm not gonna be able to assist you", I then asked why. She tells me that there's too much *****. I told her it's my first time encountering such, I've Never had to produce my ID nor Drivers licence when buying with my Mr Price card. And isn't there any other way to authenticate a client if they don't have any of the documents she asked for? I am not happy with the service Mulalo gave me. I hope Sheet Street ammends this. Not all clients walk around with an ID document or Drivers license.
