I bought a number of items at the Bayview location which were punched in individually on the iPad "cash register". Unfortunately it is impossible to verify in the moment that the amounts punched in are accurate. When it came time to pay, the amount charged to my credit card was inaccurate and was more than the total shown on the register. A manager reimbursed me after I complained but absolutely no apology was given. This is basic customer service and managers and store employees should apologize appropriately to paying customers when they make clerical errors!!! I suspect many customers are unwittingly overpaying (perhaps underpaying as well) with a payment process that relies solely on the accuracy of the cashiers' fingers.
