Customers, be aware! They tried to defraud us by pretending to not accept credit card payment!!

It’s quite disappointing since I used to go to this Pho place for the last 12 years. I finished the lunch and headed to the cashier to pay for the lunch. We had one extra large beef pho, one large beef pho, and two fresh spring rolls. Our total was $42.69 after tax as shown in the receipt. I asked if they receive Apple Pay. The asian woman who seemed like a manager said “no no”and her English was not fluent at all—I’m not sure if she was faking it to defraud money. So I was going to pay with my credit card as I saw the card reader. But then she kept asking for “Venmo Venmo you have Venmo?” I did not want to pay with Venmo at a restaurant so I said “no I don’t want to pay with Venmo.” Then she said “Zelle? Zelle?” Who pays with Zelle at a restaurant??!!! So I said “no I want to pay with my Apple Pay it’s the same as the credit card” and pointed to the card reader. Then she said “how much are you going to pay for the tip??” Since it was just a party of two there was no reason to inform the tip ahead of payment. So I said “no, if you give me the receipt I will write down the tip there.” She seemed disappointed that she couldn’t defraud us. Then she enters $42.70 when I saw on the receipt that it was $42.69. So I told her “it’s $42.69 not $42.70” she tempted to defraud us again!!! I did not want to give any tip based on her attitude and intention. But I paid $5.00 and decided I will never return to this restaurant. If she enters different amount of tip into the system, I will update the review again and take serious actions.
