******ion of money from customers

Disgusted-waiter tried ****** money out of us.Service was 5/10.we tipped him reflective of that.A tip is a gratuity/perk.he took my card&pointed to the VAT&said the tip he's left with is \nothing".So I asked him what he meant&he said once\""card charges are deducted his tip is R10\"" and something about swiping twice.he confused me&I said ok then swipe R270.00(doubling his tip).But my friend stopped him&questioned it.He said he'll bring me the card report"
