I went to pick up groceries for an elderly lady, the cashier forgot to put the grapes in one of my 3 bags of groceries plus 5 cases of lemon pop and 2 packages of toilet paper. On my way out, she reminded me to not forget all my grocery bags. Paid a total of $ 91.00 plus total. When i got to the place and we were unpacking, we found out that the grapes wasn't in the bags. I decided to go back as it cost $ 9.11 just for the grapes. The cashier is gone home, so i went to the customer service. Sorry, very poor customer service than what i used to. They were giving me the grapes, how about going back in forth on a snowy day in darkness ? ? ?
