    I had an incredibly upsetting and humiliating experience at this Dunkin’ location. I was being helped by an employee at the register and had already explained that my card might decline because I had ordered replacement cards the previous day. When the employee told me that my card had declined, another employee, **Carlos Canno**, who I later learned is an **assistant manager**, overheard the conversation. Carlos was not helping me or involved in my transaction. After hearing that my card declined, he started making a jingle and singing, **“Yo shi got declined, you ain’t got no money.”** When I confronted him about it, his explanation was, **“Sorry, it’s a TikTok.”** I then asked Carlos for the manager and district manager because I wanted to escalate what happened. Instead of helping me, he told me there were **“two Carlos,”** which only confused me further, and then told me to **file a complaint on the app or leave a review.** I found his response extremely dismissive, especially considering he is an assistant manager. The reason my card declined is beside the point. Cards decline for all kinds of reasons, and even if someone genuinely didn't have enough money in their account, **no customer deserves to be publicly mocked or embarrassed over their financial situation.** I was so upset and humiliated afterward that **I couldn't even drink the coffee I had just purchased.** I left with a drink I couldn't enjoy because I was so shaken and embarrassed by the experience. Someone in a management position should be setting the example for how customers are treated—not making fun of them and then dismissing their concerns when they ask to speak with higher management. I have filed a formal complaint regarding this incident and have video related to what occurred. I sincerely hope this is taken seriously and properly addressed.

    I always catch them at the busiest time, even with the chaos the staff is friendly and attentive. My coffee is always good and I've never had any issues with my orders.

    The people who work here are always really great and friendly! My only complaint is that they often run out of bagels and croissants on the weekends- please stock more!
