Review worst customer care

Me and my husband went to quizons sub (July 08) yesterday evening. There was 2 filipino ladies and they talking to each other in their language with so much laughing. They even didn't respect that at least we are customers. It was so irritating. My husband ordered sandwiches, when he asking questions about chips, they didn't even give proper reply, since they are busy with their laughing. We definitely won't go here after. Worst and worst customer. I have never seen this in my life.
