I tried to pay my bill, but was told that I couldn't use my credit card unless it's over $30. as per visa/mastercard agreement with the merchants, merchants CAN'T impose a minimum/maximum amount to consumers. i told the manager and the girl at the cash register. she told me it's company policy and was basically told that if i didn't like it then it's too bad. they told me they impose the $30 minimum because credit card companies charge them for the service. i told them that the whole idea of having credit card service is for the benefits of both the merchants and the consumers. and these charges to the merchants are merely the cost of doing business!
