*********** and Irresponsible staff

I was in the store yesterday to buy few things for myself when i got to the till i couldnt find my Edgars card in the purse while i was searching for my card the other cashier( Lucia) at the next till said to me, "you left your card with me last when i serve you"!!!! I was shocked when she said that then I asked her why she didnt call me immediately to alert me that i left my card at the counter with her???? She couldnt answer me she just stared at me . My question is, is not the cashier responsibility to call the customer if forget something????? Now she couldnt find my card then i left telling them to resolve it. Saddly I couldnt get my goods. Stiil waiting for the store to contact me.
