I have two issues to address. My mother ordered a turkey sub. She couldn't eat it because her teeth started hurting as she ate. So she asked if she could switch her sandwich for a meatball sub, since those are softer, and pay the difference. They told her no. So she had to buy another sub. The only reason why we stopped there for her to eat is because she is diabetic. The sandwich was so that her sugar level wouldn't get low. Then the worker asked her if she would step aside so the person behind her could order something first. She is diabetic! Why couldn't she switch her sandwich? Subway makes enough money. Where is the customer satisfaction?
