Amalgamated Bank Bella Vista Pkwy, Warrenville

I walked inside to cash a check written by Dorothy Brown's office and was immediately told I could not cash that particular check at this location. Instead, I must take the check to downtown Chicago branch to have it cashed. Considering there are only two locations. The check written did not disclose where I could or could not cash it. The check clearly says "Amalgamated Bank of Chicago." Since I live in DuPage County I chose to cash the check in Warrenville. Not sure if it was the color of my skin or Dorothy Brown's account as to why I was immediately told that the check was no good in Warrenville
