Boom Town Reno: Dealer cheat?

I've been to Reno over the holiday and played 4 red chip sessions at Boom Town single deck. The first three sessions were typical sessions with moderate wins. The pit critters were paying attention because of the spread, but there was no intervention. However, on the fourth session, it turned suspicious. I was playing with another fellow, who kept betting $2 for the dealer every hand. For first three decks after I sat down, I lost every single hand, while my neigh kept winning constantly. I played a couple more decks with one win each deck before leaving. It seemed to defy rational! Could the dealer be cheating on me?
