I don't ride CR often, but that doesn't sound right at all. You mean it costs the same to ride 1 stop into Worcester as it costs to ride from there all the way to South Station? I don't think so.
EDIT: In fact, I just checked that on the MBTA CR app and you are quite mistaken.
What he's saying is that it costs the same to go from Worcester to SS as it does to go from SS to Worcester, regardless of time.
