Even after additional baggage handlers were added to the staff in Houston’s airport, passenger complaints persisted.  The waiting times were reduced.  But what seemed to bother passengers is not how long they waited, but the fact that they has=d to wait at all.  What actually reduced passenger complaints to near zero was increasing by a factor of six the distance passengers had to walk from the gates to the baggage carousel. Social scientists deduced from this that the effort of walking carries less of a psychological cost than waiting.  Or, to put it somewhat differently, people are more bothered by the stress and boredom of waiting than by extra energy required to walk.  According to Jewish practice, a second Torah is used for the supplementary reading of maftir.  If only one Torah scroll were used, it would delay the service.  The cost of having a second Torah is less than the cost of making the congregation wait.
