Pathetic stuff and ******** mangers at shell garage

I was working at clicks in Revenue village where there is shell garage with spar. I usually buy something to drink nor airtime before I get to work. This other morning I bought airtime if r10.00 with a r100 note and I forgot to take my change back as I was in a hurry because I was late for work. When I went back the following morning ,I friendly told the lady about my story and she asked me who it was with a huge stinking attitude as she was pointing to everyone in the store. I told her it was a short guy dark in complexion and I did not even take note of his name, then she left me standing there and went to dance for this other male Co worker of hers and left me hanging. I then asked for a manager, they all said the manager is not around and some guy said who said there is managers in-store, no one's going to help you. You better live Coz we don't have time to entertain stupid people.Only to find out he was the manager I felt so stupid and unimportant as to whom to approach yet I'm a loyal customer to them. I will never forget this.
