"Excellent bobo tea mix. Expensive but I?m returning. So you want the customer to pay you for using there credit card to buy your food. Plus tip. Isn?t that why plates of food and drinks cost a certain amount to cover all the cost. I've done research on this. Each time it actually cost more to do business with cash only. Hard to steal credit card transactions. There are also other things to consider. That fee, when paid by your business, is a deductible expense at tax time. So the customer pays it, and the owner gets to deduct it. Double dipping at its finest."
