Bad attitude and poor service from a cashier with no name tag,curly short hair (Bob cut)in light brown mixed with blonde

Went to the store to buy a pack of cigarettes,gave her R50 and she gave me R1 as change with no slip went outside and realised that I normally don't buy for that amount,when I went back to query the fee and the receipt that she didn't give me she instead turned her back and faced the opposite way annoyed and very agitated,and it's not the first time she delivers such services,she is always rude unless the boss is around behind them.Her colleague Lebogang stepped in to resolve my issue and while at it,trying to look for the receipt on her system to help me.She adamantly said to her that she is taking long and she must finish as she wants to get back to work in an attitude,while she is the one that was wrong in the first place.Lebogang helped and gave me the correct amount of change and the receipt with a smile which i am thankful for.The other cashier didn't apologise for any inconvenience caused.She doesn't know anything about customer service as she is always moody,arrogant and gives attitude.
