They were out of Mac n cheese but got us some from the cooler, it was cold but they asked if we wanted to heat it up in the microwave. Said we'd just heat it up at home. Put it in the microwave for 1 minute and 30 seconds, opened it up to find the lid had melted leaving plastic in the food. Should not have suggested I microwave a non microwavable container. Called and asked them to refund our card and the gentleman on the phone was very dismissive. I get it, it's just Mac n cheese, but your customers don't want to eat plastic so we really wanted to give you a heads up that your "microwave safe" containers aren't actually microwave safe so you may want to get some new ones. It seemed a refund would be appropriate but they said we would have to come back because they don't store the cards. We don't live that close. Why can't they log in to their merchant credit card processing site (or software) and refund the transaction? Makes no sense.
