Show up to get 3 items and they were gift cards. Then was told cant check out at self checkout with gift cards so I move to a line, however only 1 line open and 8 people long at 815 am. Unacceptable. Poor management of cashiers or they need to make someone at self check out able to scan gift cards. Waiting 30 to get 2 gift cards
