Subway locations in Mercer County, NJ (Hamilton Square, Ewing, Lawrenceville, Groveville, ...)

Went in for a pulled barbecue sandwich on Satureday at 4:00pm. Noticed associate cleaning counters etc. with spray bottle.
When I placed my order, he used the same gloves to pull out bread roll. I requested him to please change gloves before serving me, he argued, and then changed gloves.
Then I asked him to replace the roll he had touched with used gloves. He refused, and to demonstrate then insisted that the store was cleaned, and picked up the cleaning bottle with the 2nd pair of gloves. This is rudest, most un-sanitory Subway I have visited. Do not recommend this store to anyone. Bought my sandwich at 3257 Quakerbridge Road, where experience was wonderful.
