Why can't the number 20 stop at the bus station?

Sheilea Mayer asked that question at the River CC meeting last week. The problem for some folk is that they need to get into town on one of the regular buses that use the A96 and then change to the number 20 to get up to the hospital. Instead of having to walk over to the stop on the High Street wouldn't it be easier for the 20 to go to the bus station as well? Here's a map of the 20 & 20a routes.
