Shared Sandwich Illness Query - The Common Man Roadside North at the Hooksett Welcome Center, Hooksett New Hampshire

530 West River Road, Hooksett, 03106 New Hampshire, United States

Boyfriend and I both shared a sandwich and fries with mayo and other condiments from the condiments station. Both violently ill at the same time around 6 hours later that lasted about 12 hours. Not 100% absolutely sure it was good poisoning, could have been a bug? But this was the only thing that just the two of us ate that could have caused it and wanted to see if anyone else experienced this. | Symptoms: Diarrhea, Nausea, Vomiting
