This restaurant really needs to work on customer service. When you go through the drive thru and it takes 3 min for someone to acknowledge you (though not s greeting) it really bothers me. When I get to the drive thru window there isn't a "hello" or "how are you" just an abrupt opening and "5.95". I used to manage fast food restaurants and I always told my team "5.95" is not a greeting. Just no excuse for not having basic customer service training. I've been all over Mexico and got warmer service even in the poorest of areas so language barrier isn't an excuse either. Yeah it's Roberto's and I shouldn't expect much but maybe they want to improve their business. Who knows.
