This guys... they manipulate the POS a lot of payment. they are check and check as if they had a cloner of cards.... I while I was serving refreshment they manipulated... and when I went to pay they gave me a price and points and I told him that I had my account they told me I already put your account... and I told him as if you don't even know who I am... and I cancel the sale I scan my things and I put my user... be very careful with that
