Over priced products and very bad customer service...

Over priced products and very bad customer service.. went to self check out sales item not in computer waited 10 mins for a staff member to Come help me . No one came ended up going to customer service desk and told the girl to cancel my order. Don't like self check outs but last time I went through a till they where rude. Managers should have a class for staff on customer service and maybe put more staff on . 2 staff on in the morning up front is ridiculous!!!
