Subway

I went to subway this morning my card was declined multiple times. I know that there is money are my cards and it kept declining meaning their card machine was down. I do not carry cash and was willing to wait until it came back up to pay for my food the works were trying to fix it and called their manager to figure out if there was something maybe they were doing wrong to fix it. I am a very loyal subway customer. Subway is my go to. Any one that know me knows that I love subway. The workers got off the phone with the manager and she asked what the manager said and the other worker said she would not repeat to a customer. Which basically means it was very rude. My question is why wouldn’t you just say see if the customer could run across the street to get cash or try to alleviate the problem. I will not be back to this subway the worker ashlynn was willing to pay for my food but I will not allow a child to pay for my food. Knowing I have money. I just think that the managers way of handling the situation was very wrong
