Yes, they are in 2 different districts, but surely it would be more efficient to have them all open on the same side.  Soon, some MBA will see that .05 seconds can be trimmed off the handling time and ensure carpal tunnel for everyone.

Or maybe having x% of the envelopes open on the opposite side actually helps prevent carpal tunnel.  Now that’s a corporate idea that would impress me.
