I had a similar positive experience in Spain and Morocco. Tangier is very close to Spain so most of the locals know Spanish.
I would always start conversations in Spanish. Most of the time the person I was talking to would appreciate my attempt and switch to English. In Tangier I talked to a street peddler for over 15 minutes while friends were in a store. I attempted to speak in Spanish but he preferred English. He just wanted to chat.
